In this crossover anime, I've been bound to two systems.

Perhaps because she felt emboldened by speaking her mind, she gradually stopped obeying you, and her behavior began to resemble that of her adolescence.

She's stopped calling you "brother" and is now addressing you by your first name. She's gradually encroaching on your comfort zone, no longer leaving you alone at home, and is half-dragging, half-forcing you to go out with her.

As time went on, she began to control your intake of cigarettes and alcohol.

Not only that, she also dragged you along for morning runs, shopping, dining at restaurants, and watching movies together.

Even if you refuse, it's no use. She'll use every trick in the book—persuasion, pleading, tantrums—to make you helpless.

[Iroha has also explicitly instructed you to start participating in household chores.]

In your apartment, first a cat appeared, then a pair of rabbits, and later a dog.

Iroha Isshiki is becoming increasingly intimate with you; your long period of living together has made her accustomed to your presence in her world.

Ever since she noticed your unusually strong physical reaction when she woke you up that time, her feelings for you, which she had never had a romantic relationship with before, have slowly begun to change, becoming something entirely different.

[She herself didn't realize that she had started to enjoy watching you struggle in the mornings and playing around with you in bed.]

There's a subtle, inexplicable feeling between you two.

You have repeatedly ordered her to leave your apartment and go home, but she has dismissed your orders with a nonchalant attitude.

[A year later, after you finished dinner and played games with Iroha Isshiki, it was late at night. You washed up, lay down in bed, and closed your eyes. In the middle of the night, you vaguely sensed Iroha Isshiki crawling into your bed.]

[Immerse yourself in the story from a first-person perspective...]

The room was lit by a small, orange nightlight.

Suzumiya Chisato slowly opened her eyes and met Iroha Isshiki's somewhat timid and shy gaze.

"what are you doing?"

"It's so cold today."

As Isshiki Iroha spoke, she tried to snuggle into Suzumiya Senri's arms.

Suzumiya Senri pushed her away, simultaneously stepping back herself.

Go back to your room and sleep, turn on the air conditioner.

"No... I don't want to go back. It's cold even with the air conditioning on. It's warmer under your blankets."

"..."

Suzumiya Senri remained silent for a long while.

"Then you sleep here, I'll go to your room."

"No, not together!"

Isshiki Iroha boldly clung tightly to Suzumiya Chisato's arm, preventing him from leaving.

Suzumiya Senri stared at her.

Do you know what you're doing right now?

“I know, my sister-in-law told me to do it.”

"I am your brother."

"But there is no blood relation."

"..."

Suzumiya Chisato didn't want to say anything more to her, so she turned her back to her.

This reaction frightened Isshiki.

She tentatively reached out her hand, but Suzumiya Senri slapped it away.

Isshiki felt somewhat wronged.

Lately, her interactions with Suzumiya Chisato have been very warm and harmonious, and she believes that he should have moved on from what happened back then long ago.

I thought my initiative tonight would bring us closer, but now it seems that's not the case at all.

Something was overlooked.

Iroha Isshiki slowly sat up in bed and left the room.

The door behind her was slammed shut.

She turned around angrily and muttered "stinky Qianli" under her breath.

On her way back to her room, she held her chest with both hands and let out a long sigh.

Chapter 147 You've Got Your Wish

You remain true to the persona you've created for yourself, repeatedly reminding yourself that you're almost there, and you absolutely cannot reveal the slightest flaw.

Although you successfully lured Isshiki Hatake into the cage you had woven by using the note left by your wife and your recent listless behavior, you remained calm. You understood that the care stemming from your guilt was not an unbreakable bond.

Fortunately, Isshiki Hachiman is finally starting to see you as a man, and so much time has passed since his beloved wife "passed away," so you are slowly beginning to recover.

Having grown up with Iroha Isshiki, you clearly understand the qualities she admires in a man: clean, devoted, gentle, family-oriented, ambitious, and most importantly, unconditionally good to her.

By adhering to these qualities, you begin to embody the ideal man she admires. You strive to become her ideal self and win her love.

[You've started going out more often, returning to a normal routine, exercising, finding a new job, and occasionally going back to the Isshiki couple's place for meals, chatting and laughing with them. During holidays, you even take them and Iroha on trips together.]

Your renewed spirits have brought immense comfort to the Isshiki couple. They've also noticed the somewhat unusually close relationship between Isshiki and you, but they've remained silent, tacitly acquiescing about it.

[They remembered your affection for Isshiki Iroha from many years ago, which is why they rejected their friend's idea of ​​introducing their son to their daughter. After Mrs. Isshiki spoke with her daughter privately and noticed her slightly flushed face and shy expression, she began to secretly try to match you two up.]

[Lady Isshiki doesn't allow the clueless Mr. Isshiki to interfere, and under her absolute control, the process of you and Iroha Isshiki gradually becoming closer proceeds quite quickly and smoothly.]

[When you come home for dinner in the evening, Mrs. Isshiki always asks you to stay overnight. After you agree, the Isshiki couple either have something urgent to do and need to go out, or a friend suddenly invites them to dinner. In short, you and Isshiki are left alone at home.]

As these situations became more frequent, Iroha Isshiki gradually began to realize her parents' thoughts. At first, she was a little embarrassed, but as time went by and her mindset changed, she no longer saw you as just a brother, and she quickly began to discover your charm as a man. Your looks and physique go without saying, and your personality is also excellent.

The wonderful qualities she discovered in you captivated Isshiki Iroha. Realizing her unusual affection for you, she gradually began to take the initiative. She would use the excuse of being afraid of horror movies to pull you into a small, dimly lit living room sofa, where you would both snuggle together under a small blanket, your skin pressed together.

[Then, halfway through the movie, she'll show an expression of utter panic, desperately trying to snuggle into your arms. Finally, as the movie ends, she'll close her eyes, refusing to open them no matter how much you push her, until you carry her back to the room, constantly closing the distance between you two.]

[Iroha Isshiki's guilt and the sense of responsibility entrusted to her by her sister-in-law began to subtly transform into pure love.]

As you predicted, your relationship with Isshiki Hachiman is progressing rapidly, subtly and gradually.

[In the amusement park bathed in the afterglow of the setting sun, as you reached the highest point on the Ferris wheel, Iroha, taking you by surprise, gave you a shy yet proactive kiss. From that moment on, your relationship began to accelerate rapidly.]

[Your excessive concern for your "deceased wife" and the resulting regret and hesitation only make Isshiki Iroha like you even more. She has repeatedly stated that she has no intention of replacing your sister-in-law, and that it doesn't matter if you can never forget her, she just hopes that you won't resist her presence because of it.]

Having made her feelings clear, Isshiki Yuu's offensive intensifies; she begins to flirt and tease you regardless of the situation.

[In the mall's fitting room, she pulled you in and helped you unzip the back of her dress; on the overnight bus during a trip, she secretly touched your stomach and thighs; at the fireplace, she started gently rubbing her foot against your calf in front of your parents.]

After a company dinner, Isshiki Iroha picked you up in her car. Back at your apartment, you were quite drunk and went straight to your room, collapsing onto the bed. But Isshiki Iroha wouldn't let you get up and drag you to take a shower.

Seeing Iroha's unusually shy expression, you realized something might happen tonight. Still pretending to be tipsy, you took a shower, returned to your room, and closed your eyes, feigning sleep.

Half an hour later, you heard a "click" sound coming from the bedside table. Puzzled, you peeked through a crack in your eye and saw Iroha placing a photo of you and your wife face down.

[Having made up her mind, Iroha came to your side and gently lay down, tenderly calling your name.]

You ignored her soft call, and the next moment, the girl pressed herself against you and kissed you.

[You can no longer pretend to be asleep. A mischievous smile, like a little devil, spread across Iroha's face. Seeing you open your eyes, she lay down beside you, incredibly shy yet unusually bold.]

Tonight, she finally put to good use the knowledge her mother had taught her.

The feelings born in childhood, which then sprouted and grew into an unrequited love during adolescence, have finally come to an end after so many years of patience and planning, allowing you to obtain what you've always dreamed of!

Your sanity has collapsed.

[Your actions towards Isshiki Hatake gradually changed from being extremely cautious, as if you were afraid of breaking her, to becoming more and more relaxed and at ease.]

[As Isshiki Yui kept calling your name, you and she confirmed your relationship, officially taking that step as you wished.]

The next day, you and she slept in until 3 PM, and Iroha felt she loved you even more.

A month later, Iroha Isshiki was surprised to find herself a ##.

You proposed to her on her birthday, and your wedding was a joyous occasion, receiving many blessings.

But you seem to have caught a glimpse of someone who absolutely shouldn't be here.

This chapter has been revised.

Chapter 148 (Final Chapter)

You saw your wife, who should have "left this world," appear at your wedding with Iroha Isshiki.

Even though she was wearing a baseball cap and a mask, you, who knew her so well, recognized her at a glance.

[You are terrified by this; the Central American custom of faking death should not be included in your wedding.]

What does she want to do here? Cause trouble? Make a scene? Expose her own scams from all these years in public?

You were filled with terror, unable to understand her purpose in coming here.

[In recent years, every few months you would secretly meet with Zhong Meili under the pretext of business trips. She has always loved you deeply, unconditionally obeying everything you say and do, and still craves the pain you inflict on her, which makes her even more aroused and excited.]

She's the same as before, unchanged, just as you always firmly believed.

[A strong urge to get Midori to leave surges within you, but at the wedding, you are the center of attention, and your every move is under the watchful eyes of others. Therefore, you cannot directly approach her, nor do you trust anyone but yourself to do so. Thus, you can only suppress your unease and, under the watchful eyes of Midori, who is positioned in a corner, exchange vows with Iroha Isshiki, exchange rings, and complete the entire wedding ceremony.]

After the wedding, you arrive at the banquet hotel but find no trace of Mid-American Wedding. You seize the opportunity to leave temporarily under the pretext of entertaining your colleagues, and find a private and safe place to dial Mid-American Wedding's number. However, all you hear is a message saying "The other party's phone is switched off."

Unable to contact Mid-American Rei, you grew increasingly uneasy, but you concealed your feelings and tried your best to be cheerful and natural as Iroha linked arms with you, spending the most brilliant and beautiful day of her life.

After the wedding, with a week left for their honeymoon, Iroha happily bought beautiful clothes online and a brand new camera, wanting to record the scenery along the way as a keepsake, and also to show it to her future children.

[You originally requested a two-week leave from the company, but due to the North American etiquette, you told Isshiki Iroha that the company was very busy with a lot of external business and you needed to go back to help.]

[Iroha pouted, not very happy. She didn't want to be separated from her newlywed husband and wished she could stay by his side all day. After his repeated assurances that it wouldn't affect their honeymoon, she reluctantly agreed.]

The next day, you went to the company, volunteered for the business trip, and immediately went to the secret apartment you had prepared for Mid-North America, far from Tokyo.

The moment you pushed open the apartment door, a sense of unease crept in. Much of the furniture and decorations were gone; the room was empty, like a rented apartment ready for occupancy.

A letter lies on the floor in the center of the living room. You pick it up and open it.
