His physiological preference

Qin Yushang walked into the living room and sat down on the sofa.

Qin Yushang leaned back on the sofa, staring at the ceiling. His brother's bedroom door was tightly closed.

He felt he shouldn't be there, but he was also curious about what had happened. Was his brother alright? Or was he planning to commit marriage fraud?

It was getting dark outside. The lights in the living room were off, but the light streaming in through the floor-to-ceiling windows bathed the entire room in a grayish-blue hue.

The aroma of food wafted from the kitchen, neatly arranged on the table with two sets of bowls and chopsticks.

So they're living together? But there are so few of a woman's belongings in the house.

And wasn't this the girl who just said on the first floor that her boyfriend was worse than a loan shark?

So it was her brother who forced her?

In the bedroom, Qin Yuzheng gently placed Yang Zhiyan on the bed.

He knelt on one knee by the bed, supporting himself with one hand on her side and holding her hand on his knee with the other.

He looked down at her, his expression shifting quickly from anger to grievance. Yang Zhiyan thought she had met an Oscar winner.

"Baby, I'm jealous," he said softly, almost like he was being affectionate.

The leader, who instilled fear in countless people in officialdom, knelt on one knee by the bed, held his girlfriend's hand, and said he was jealous, his voice tinged with grievance.

Yang Zhiyan was still immersed in the shame she had just felt. She kept her head down, not daring to look at him.

"Who is he? How does he know your house password?" she asked, her voice muffled.

"He's my brother. Actually, the house next door belongs to him," Qin Yuzheng said. "The password has never been changed. I told him it before."

When Qin Yuzheng said this, his aggrieved expression turned into gritted teeth, as if he wished he didn't have this younger brother.

Yang Zhiyan finally looked up at him. "I thought it was you who came back."

Yang Zhiyan looked up and met his eyes. "I want to hug you."

Upon hearing this, Qin Yuzheng's aggrieved expression lessened slightly. His lips twitched, as if he wanted to say, "That's more like it," but he didn't.

"I'm still jealous," he said. "You've been hugging other men. What if you don't want me anymore?"

He was genuinely afraid. Qin Yushang was younger than him, and Qin Yushang was also very outstanding. At less than thirty years old, his company was already worth tens of billions.

Although he was also quite wealthy, inheriting money from his grandmother and receiving dividends from the Qin family, earning several million annually, it paled in comparison to Qin Yushang's wealth. Therefore, in terms of both wealth and age, Qin Yushang was far superior to him.

Yang Zhiyan was the person he had waited thirty-five years for, and he could not accept any possibility of losing her.

Yang Zhiyan looked at him. His eyes were red and swollen, like a big dog abandoned by its owner.

She reached out and patted the back of his hand. "Don't be so petty, we're nothing. We just bumped into each other, and then you came back."

Qin Yuzheng looked at her with a skeptical expression before finally stating his conditions.

"Can I have a kiss?" he pleaded.

But before Yang Zhiyan could speak, his lips had already landed.

The kiss was urgent; it captured her lips directly, with an irresistible force, as if asserting dominance or confirming her continued presence.

His hand slid from her shoulder to her waist, his palm resting on her waist, his fingertips gently pressing against it through the fabric of her shirt.

Yang Zhiyan's body went from stiff to soft, becoming as limp as a puddle of water.

Her fingers gripped the shirt at his chest. His kisses moved from her lips to the corner of her mouth, and from there to her earlobe.

His breath brushed against her earlobe, warm and rhythmic with his own.

Yang Zhiyan closed her eyes. Something was burning inside her body, starting from her heart and spreading through her blood vessels to her limbs and bones.

Then she felt it.

A surge of heat welled up from below; it was my period, overwhelming me.

Yang Zhiyan froze, and she pushed him away abruptly.

Qin Yuzheng was pushed backward by her and only managed to steady himself by bracing himself on the bed.

"What's wrong?" Qin Yuzheng asked, puzzled. She had never reacted so violently, pushing him away so forcefully before. Could it be...?

Yang Zhiyan didn't answer. She pushed him away, got out of bed, and quickly walked into the bathroom. The door closed.

Qin Yuzheng sat on the edge of the bed, listening to the sound of water coming from the bathroom.

He looked down and saw a small dark red stain on the bed sheet.

Oh, I see... My mood improved a bit.

The warmth of her touch still lingered on Qin Yuzheng's lips. Her fingers, which had been gripping his shirt tightly, had loosened, but the shirt at his chest was still wrinkled from being squeezed.

The bathroom door opened. Yang Zhiyan came out, her face still wet with water droplets, and her lips paler than before.

She stood at the bathroom door, looking down at her toes, not daring to look at him.

"I..." She opened her mouth, but didn't know what to say.

She just changed her sanitary napkin in the bathroom, washed her face with cold water, and took a dozen deep breaths in front of the mirror.

But when I stood in front of him, all my mental preparation crumbled.

Qin Yuzheng stood up and walked up to her.

He reached out and pulled her into his arms, placing one hand on the back of her head and pressing her chin against his shoulder. Her face was pressed against his neck, and she could feel his pulse.

"It's fine,"

His voice came down from above her head, low and steady, with a reassuring certainty: "I'm here."

Yang Zhiyan buried her face in his shoulder and stopped talking.

He held her and stood at the bathroom door for a while. It was already dark outside. He bent down and kissed the top of her head.

"I'll wait for you outside," he said, releasing her. "Take your time to get ready. No rush."

He walked to the door, opened it, and went out. The door closed softly behind him.

Yang Zhiyan stood at the bathroom door, her hand still in the same position as before.

She walked to the bedside and saw the dark red stain on the sheet.

She squatted down and touched the mark with her finger; it was already dry.

The first time I went into his room, I stained the sheets. It was embarrassing to tell anyone, and actually quite awkward.

Ah~ Yang Zhiyan, what did you do today? Why didn't you just go back to her place?

In the living room, Qin Yushang sat on the sofa. He had been sitting there for quite a while, recovering somewhat from the initial awkwardness, and began to think about what to do next.

Should he leave? He wants to gossip about his brother's private affairs. Should he stay? What if he gets beaten up for ruining his brother's plans?

Hearing the bedroom door open, he immediately sat up straight, ready to stand up and say "I'm leaving now" at any moment.

When Qin Yuzheng came out of the bedroom, Qin Yushang's gaze first fell on his face, and then he noticed that his brother's lips were red.

It must have been a very intense kiss just now; the skin was slightly red and swollen, glistening with moisture under the light.

Qin Yushang's gaze lingered on his lips for a moment. Then he thought, how long had his brother been inside? Ten minutes? From the moment his brother entered until now, it had been less than fifteen minutes at most.

Subtracting the time spent on comforting and explaining, Qin Yushang did some mental calculations and felt that the remaining amount was not quite right.

But then he thought, given his brother's condition, it would be good enough if he could even manage.

His family used to think he couldn't do it, but now it seems he can manage, not that he can't, but that he can barely manage.

Qin Yushang pondered these thoughts for a moment, his expression unchanged, but he didn't know if his brother's sharp eyes would notice.

Qin Yuzheng's gaze swept across Qin Yushang's face, and he snorted coldly.
