Didn't you go to Teyvat to earn money to support me?

As Siegfried pondered this, he opened the briefcase beside his bed, inside which lay the usual pale blue reagent. This was a gift from Otto's medical unit; it contained an egg cell cloned from her and Cecilia's genes. Theoretically, injecting this into her body would give her a chance, as a woman's instincts would allow the uterus to accept it, and the egg cell would develop into a human.

This method is called in vivo cloning, essentially similar to in vitro fertilization (IVF). The only difference is that the egg cell doesn't develop from the union of sperm and egg, but rather from a clone of a somatic cell. Therefore, since the genes for this reagent came from Siegfried and Cecilia, the child can only be a daughter.

The children of two women will only be daughters.

Siegfried looked at the reagent that would become her daughter, then put it away.

There were two doses of the reagent, one for Cecilia. Even during the wedding, Cecilia would likely play the role of the "wife," while he would be the "husband," but both of them would inject themselves to increase their chances of conceiving. According to her menstrual cycle, Cecilia was most fertile the night before the wedding, but her fertile window was difficult to pinpoint due to her long-standing male-dominated lifestyle, as she was so unpredictable that even her menstrual cycle was irregular.

But it doesn't matter, she'll choose to get the injection together with Cecilia...maybe they can both have a daughter then?

Siegfried even thought about what to name them. During their month-long trip together, she and Cecilia imagined the future. If they had one daughter, they would name her "Kana" (Moon Goddess). If they had two daughters, they would name them... "Sirin" (Sky Queen).

Although they were a bit cringey, surprisingly Cecilia actually thought they were pretty great.

Upon reflection, Siegfried understood. After all, the aesthetics of these ancient, timeless families like Schicksal were probably just that old and outdated. What modern people considered cheesy names were traditional virtues in their eyes. For example, his own name was "Siegfried," Bubu's name was "Brynhild," and Claire's name was "Claire."

Even Cecilia's own name, though seemingly ordinary, actually means "pure and carefree angel (cecilia)" upon closer examination.

The more she thought about it, the happier she became. Siegfried couldn't help but roll around on the bed with her pillow in her arms. Then she took out her phone and secretly connected to the hotel's security cameras.

Of course, Siegfried trusted Cecilia completely, but she was actually a little worried about Shigure Kira. Now that Cecilia was living alone with Shigure Kira, the little girl would most likely find an opportunity to take advantage of her, the saintess.

Since he had nothing else to do, Siegfried simply pulled up all the hotel's security camera footage. Cecilia had only returned to the hotel yesterday noon, so it had only been a day and a half; a quick glance at it wouldn't take more than a few minutes.

The surveillance footage started jumping forward and soon returned to the normal view.

Yesterday at noon, Cecilia returned to her hotel after getting off the plane and chatted with Shigure Kira; nothing happened.

In the afternoon, Brunhilde was dismissed from school. Two girls came out to greet her and take her home. Brunhilde then cooked dinner, making spaghetti bolognese, presumably as a welcome-back meal. Siegfried knew Brunhilde always had a touch of inexplicable stubbornness.

Halfway through the meal, Cheng Lixue arrived and provided two sets of chopsticks and bowls. The four of them then sat happily in the living room watching cartoons on TV.

Siegfried skipped a few steps, and then time quickly moved to night, with everyone going back to their rooms to sleep. Siegfried had originally intended to skip directly to the next morning, but as she swiped through the playback, she suddenly paused, seeing an interesting scene.

The time in the upper right corner showed 2 a.m. Brunhilde walked out of his room barefoot, went to the bathroom in a daze, then took a glass of iced water from the refrigerator, drank it, shook his head, and went back to his room in a daze.

They returned to Cecilia's bedroom.

Siegfried chuckled, flipped the book over, and looked at it again. The little Ragdoll cat was weak; it always had low blood pressure when it woke up, and it was especially disoriented when it got up at night, so it would often do some very cute things. For example, it would go out without wearing clothes, bump into door frames, or fall asleep in someone's arms, leaving them at a loss for what to do... and so on.

But because it's so adorable, Siegfried often doesn't want to remind him when this happens. Seeing him clutching his clothes, snuggling in his arms, and sleeping soundly makes him feel like his energy is about to drain.

But as Siegfried looked around, a hint of hesitation crept into her mind. She knew that Bubu often slept with Cecilia, and even if she was discovered to have gone to the wrong place, she probably wouldn't bother to come out and would just go along with it. But this time, Siegfried's keen intuition told her that something was amiss.

She and Cecilia had been away from home for a month, and Cecilia and Brunhilde hadn't seen each other for a very long time either, so their dependence on each other must have grown stronger.

Siegfried knew that these past few days had been Cecilia's... happiest time, which, in layman's terms, was her fertile window. Girls often become much more docile during this period, as it's typically the most fertile time of the month. Genetic instincts make girls particularly clingy and proactive during this time. Even though Siegfried, being a girl, hadn't experienced Cecilia's initiative, Brunhilde was a boy.

Siegfried was a little worried that the night might not be peaceful.

After all, Brunhilde has grown a year older. Although her appearance hasn't changed, she's now a fully developed teenager. No matter how much she trusts Boubou, can she truly trust her instincts? What if Boubou accidentally wanders into the wrong room and sees a beautiful young woman? Would he have a moment of madness and commit a terrible mistake?

Siegfried turned on the bedroom camera again, which Claire had suggested she install.

She felt a pang of guilt about this, because it meant she didn't trust Brunhilde. In truth, she was always somewhat wary of the little Ragdoll cat. Although it was rather unreasonable for an older sister to be wary of her younger brother, and she sometimes felt ashamed in the face of Bubba's aloof and harmless face, her intuition always reminded her... As a member of the Kaslana family, Siegfried's intuition had always been accurate, except when it came to Brunhilde.

But she had actually told Cecilia that she had installed a camera. After all, if Cecilia discovered the camera without her prior notice, it would lead to a huge misunderstanding. However, she generally didn't look at the camera; there was nothing to see anyway. Cecilia slept very upright and didn't talk in her sleep, so there was nothing to see. Therefore, she usually looked at Brunhilde.

Even though the little Ragdoll cat knew there were cameras, it didn't care at all about how it appeared in its sister's eyes.

So this was the first time Siegfried had seen Cecilia's bedroom.

Switch channels and play.

Women experience two peak periods of clinginess during their monthly cycle: one is during the first few days of their fertile window, and the other is about fourteen days later. During these peak periods, libido surges, sometimes causing loneliness and sleepless nights, requiring willpower to suppress it, or exhaustion to prevent them from thinking about these things.

Siegfried was surprised to find that Cecilia seemed to be sleeping very soundly tonight.

She was speechless. Perhaps this was the advantage of being a virgin. Cecilia didn't understand the messy things between men and women at all. Even when she reached her period, she didn't feel like there was anything wrong with her, so she was able to sleep soundly without any problems.

After the little Ragdoll cat came in, it habitually climbed onto the bed. Then, perhaps because it was exposed to the different feel of the bed, it paused for a moment, as if it had come to its senses.

The surveillance footage showed Brunhilde looking somewhat flustered, seemingly wanting to get out of bed but worried about making a sound. Siegfried understood her concerns; making noise and waking Cecilia would make it seem as if he had been discovered during a night raid…

After hesitating for a moment, Brunhilde lay down properly, not touching the pillow, and carefully tried not to make a sound.

It lasted for about twenty seconds. Perhaps it was indeed a bit cold outside. Brunhilde pondered for a while before quietly pulling back a crack in the blanket covering Cecilia. But Cecilia had covered the blanket too tightly, and Brunhilde could only pull it open a little. She couldn't get in; she could only stick one leg in, with half of her body still exposed, shivering.

Siegfried wanted to laugh.

Then, Cecilia gently rolled over, changing from lying on her back to lying on her side facing Brunhilde. This movement seemed to casually place her hand on Brunhilde's waist. In doing so, the blanket was pulled up quite a bit, leaving Brunhilde with only her legs exposed, most of her body now covered by the blanket.

That's warm enough. Actually, most of the time, as long as your stomach is covered, you won't feel too cold. Getting chilled mainly happens in the stomach. As for your arms and legs being outside, it doesn't matter; you can sleep there.

Siegfried was relieved that Cecilia turned around in time; otherwise, given Bubu's trouble-averse nature, he might have really been freezing all night.

But Siegfried knew he was wrong as soon as he turned his attention to Cecilia.

Brunhilde was lying on her side with her back to Cecilia, so she didn't know that Cecilia had emptied her arms. However, Cecilia had already opened her eyes. Although her eyes were full of surprise, she still casually picked up the little Ragdoll cat and covered it with a blanket, so that Brunhilde wouldn't notice that she was awake.

Brunhilde seemed extremely nervous because he was being hugged around the waist; he remained stiff and motionless.

Both the man and woman were unable to sleep for different reasons. Brunhilde was worried that her movements would wake Cecilia, while Cecilia playfully took care of this silly little cat who had somehow ended up on her bed.

Siegfried grew increasingly uneasy as she looked around. Although nothing had actually happened, she had a bad feeling.

Time ticked by, and Siegfried knew that Brunhilde was trying to distract herself. A boy her age was surely wide awake, filled with annoyance, anxiety, and the restless heat of puberty. He kept his eyes closed, trying to keep his breathing steady, pretending to be fast asleep.

Perhaps sensing that Brunhilde had fallen asleep enough, Cecilia's expression changed, and she glanced at the camera.

Siegfried's heart skipped a beat; she wondered if Cecilia had suddenly remembered the camera.

What does this mean...? Siegfried's mind was a little confused.

But Cecilia seemed to only glance at it casually, and then she slowly got up, and without disturbing Brunhilde, she slowly pulled back the covers, revealing her beautiful body in only her underwear, with long white hair hanging down on her chest.

Siegfried swallowed, suddenly feeling annoyed.

—Was Cecilia holding Brunhilde in the blankets like that just now? Was her body in contact with Brunhilde's back like that?

—That's so enviable!

Cecilia carefully turned around and then sat up. The weather had been rather gloomy last night, with no moonlight and it was very dark outside. The camera had night vision, so everything was clearly visible, but perhaps Brunhilde's mortal eyesight was completely blind, or at most, he could only catch a glimpse of the general outlines of things. He would never have known that Cecilia was gazing at him.

Siegfried could see very clearly. Cecilia knelt quietly beside Brunhilde, rubbing her eyes a few times, seemingly trying to see more clearly in the dark night.

She got up slowly, but how could Brunhilde, who had been sleeping in her arms, not feel it? Siegfried noticed that when Cecilia got up, the little Ragdoll cat's expression furrowed slightly, as if it was unhappy about losing the warm embrace behind it, but it quickly returned to normal. It probably thought Cecilia was about to get up to use the bathroom, so the little Ragdoll cat kept its eyes closed and pretended to be asleep.

After waiting for at least a minute without any movement from Cecilia, Brunhilde seemed to sense something was amiss. His eyelids twitched slightly, as if he wanted to open his eyes to see what the saintess beside him was doing, but he was still worried that Cecilia would find out he wasn't asleep, so he ultimately didn't open them.

He was of course unaware that everything about him was under Cecilia's control. In fact, even in complete darkness, an S-rank Valkyrie could clearly see Brunhilde's micro-expressions.

Siegfried knew this was a recording from last night, and now, filled with tension and fear, she just wanted to see what happened.

Chapter Sixty: Letting the Wolf In

She vaguely recalled many strange things that had happened in the past six months, things that her intuition told her were wrong, but which she was unwilling to associate with.

Instead of biting fingers, they bite the neck to suck blood. When I came home, I saw the two of them hugging and feeding each other. They taught each other how to cook in the kitchen every day, but I still couldn't learn a single dish in half a year. When riding horses on the Alpine coast, the two of them looked radiant. Thinking about it carefully, is this really something that a "sibling" couple who have only known each other for half a year should do?

As her real sister, Brunhilde... well, that's about it.

Why didn't she notice it all this time?

But it's too early to say anything now, Siegfried reminded himself. It's too hasty to draw conclusions now; it's just some minor movement while sleeping. Cecilia and Brunhilde might just have a weak sense of boundaries. Yes, they were like that from the beginning, and after they changed, I still encouraged them to spend more time together.

Brunhilde was raised like a girl, so it's normal for him to have a weaker sense of distance. It's also common for him not to notice overly intimate behavior; after all, he raised Bubu himself, and even in his teens, he wasn't used to avoiding suspicion. Cecilia probably had no problem either. Coming from a lineage of saints, she'd never seen a boy before, so it's understandable that she subconsciously mistook Bubu, a boy with such a deceptively attractive appearance, for a girl. It was just some intimacy, nothing serious…

At this moment, Cecilia rubbed her eyes and felt that her vision seemed to be much clearer. She revealed a very sly smile, licked her lips, and then slowly bent down.

She kissed the boy's fair nape.

Siegfried instinctively turned off her phone. She felt a tightness in her chest, and even a little short of breath. After a long while, she turned her phone back on and continued looking at it.

She reassured herself that it was nothing, and that kissing and hugging were still perfectly reasonable. Even in front of her, Cecilia would sometimes get carried away and grab the little Ragdoll cat for a flurry of kisses, sometimes even making Brunhilde annoyed and kick her.

Miss Saintess often couldn't suppress her affection for Bubu, perhaps because she had several younger sisters in her family and was used to being an older sister, so she had an instinct to care for and love human cubs.

Anyway, Cecilia had done kissing many times before, so she was quite skilled at it. So in the video, after kissing him, Cecilia looked at Brunhilde, who was still pretending to be asleep, with a smile in her eyes. Then she lifted his blanket, hugged him from behind, pulled the not-so-large Brunhilde into her arms, and gently bit his earlobe.

Siegfried saw it clearly: as Cecilia approached his ear, Brunhilde seemed to feel the warmth of the little saintess's breath behind her. The surveillance camera couldn't see if his face turned red, but it did see Brunhilde's originally relaxed fingers curl slightly, as if she had already sensed something.

"Um……"

The little Ragdoll cat let out a soft whimper as his ear was bitten. Cecilia's bite was gentle and sweet, and the moment she actually sucked on his earlobe, Siegfried could even clearly see Brunhilde's fingers immediately clench the sheets, but Cecilia didn't even notice this obvious movement.

She was probably focused on nibbling the boy's ear, her smile both alluring and playful.

She knew Brunhilde was pretending to be asleep; she knew it all along.

Cecilia lay on her side, embracing him, her right arm around his waist, positioned directly in front of him—a position where the camera couldn't see what she was doing. The little ragdoll cat curled up in the saint's arms, its body arched like a little shrimp.

He only opened his eyes when Cecilia gently nibbled at him, his eyes filled with panic and a hint of inner turmoil. Siegfried had expected his younger brother to immediately rush out or say something to warn him, but slowly, several seconds passed, and after what seemed like a long internal struggle, he closed his eyes and held back.

He even shifted his body slightly to allow Cecilia to get closer to him, and his grip on the sheets loosened little by little, letting the white-haired little saintess behind him gently stroke his waist with her right hand.

A boy's head and a girl's waist are not to be touched casually, but in Siegfried's mind, his adorable younger brother had always been a magical being "between male and female." Brunhilde, in her interactions with them, was even more like the "girl" on the other end. Seeing Brunhilde no longer struggle and allow Cecilia to touch and kiss her, she knew that Brunhilde had tacitly approved of Cecilia's unbridled behavior towards him.

Seeing this, she felt a pang of pain in her heart. What exactly was this all about?

Yes, it's not uncommon for Brunhilde and Cecilia to kiss like that; it's just a way of expressing affection by kissing on the cheek, and Scandinavians don't find it taboo.

But is such a tender kiss really the same as those kisses on the cheek? Is Cecilia expressing familial affection for Brunhilde? This level, this posture, this action... it's blatant blasphemy.

Why didn't Brunhilde resist?
