Crossover: I Took In a Runaway High School Girl

That's right, Yukinoshita Yukino reported Yuki Suou. Then Renji carried the girl and placed her at the door. Yukinoshita Yukino said that she didn't want to stop Yuki and Renji from having a relationship. She just wanted Yuki Suou to be more calm.

For a relationship, it's better to let it flow. After all, if Renji really wanted Yuki Suou, he would have done it a long time ago. Renji didn't do that. That meant he cared a lot about this younger sister of his. In that case, she, who was going to be engaged to Renji, also had to cherish this sister.

If Yuki Suou knew what Yukinoshita was thinking, she would definitely roll her eyes and say, "Then, thank you!"

Even though she was kicked out, Yuki Suou wasn't depressed. For her, attacking and seducing Renji was a way to strengthen their feelings. It was also her own pleasure. If it was too easy, people wouldn't feel challenged. She had to make Renji like her very much!

"Brother, open the door! Yuki is here to bring you some tea!" At nine o'clock at night, the girl's cheerful and pleasant voice was heard at Renji's door.

He opened the door, and everything seemed dark, with only the reflection of moonlight from the window.

"What tea are you bringing me this late?"

"This is a special herbal tea someone made to reduce internal heat..."

"Reduce internal heat? Let me try."

A dragon's physique has its good and bad sides. Renji was also very depressed because he was easily 'aroused'. Although Mahiru, Sayu, and Kamiigusa Misaki liked his condition, he couldn't just mess around every day. They also needed to rest. Frieren said this was caused by his unstable increase in magic power. Maybe, he had to adjust his power again in a few days.

Now, let's try the herbal tea from his cute younger sister. He raised the teacup and took a sip, showing a satisfied expression. "Not bad, Yuki, very refreshing!"

"Hehe, right! This is a recipe I bought for a lot of money!" Yuki Suou said as if presenting a treasure, then approached shyly and hugged him.

"Brother, who slept in your bed today? There's a familiar scent."

Renji raised his hand to stroke her hair and smiled, "Who else would get into my bed besides you?"

"Hmph, isn't there Mashiro? I knew this morning! She said she was eating some delicious food!" Yuki Suou pouted and looked at him in dissatisfaction.

"Mashiro can eat, Yuki can eat too! I'm just asking if you're going to give it to me!"

Renji had a headache. Was this a question about being given or not? Facing the active, lively, and cute Yuki Suou, of course, he was tempted. But after his memory recovered, his feelings for Yuki Suou were not just physical urges, but a love as an older brother.

"Alright, honey, you'll get it, but not now. Yuki, this is our house, we'll always be together. There will be a chance, right?"

When Yuki Suou heard this, her heart melted. "Brother, I'll listen to you!"

"Good, now go to sleep obediently!"

Around ten o'clock at night, Renji went to the bathroom. When he returned, he found a warm body inside the blanket.

"Yuki? You planned this, didn't you?" Renji remembered the herbal tea from earlier, and his face was filled with exasperation.

"Hehe, that herbal tea also has a diuretic effect, Brother. I won't hurt you." Yuki Suou smiled naughtily. "It's just... Yuki misses you so much. It's been so long, hug me and sleep together."

They were used to this. In the past, it was Renji who insisted on sleeping with her. And the formerly whiny Yuki naturally enjoyed his warm embrace. Renji stroked her hair, feeling the familiar touch on his chest. "Be a good girl, go to sleep. I'm here."

Yuki Suou rubbed her cheek against Renji's chest and took a deep breath. "Brother, you must always stay energetic."

"I'll also help with Yukinoshita!"

Renji was a little amused. "What are you going to help with?"

"Hehe, because Yukinoshita is so interesting, she's so cute when she says one thing and means another." Yuki chuckled. "I can accept being a family with such a beautiful person, but... Yuki has to be the only one for Brother, otherwise I won't approve of your relationship."

"Nonsense, you've always been the only one, my cutest sister."

"My cutest sister, that's always been the case!" Yuki Suou's eyes were glistening. It had been more than ten years since her brother had called her by that affectionate nickname.

"Alright, be a good girl and go to sleep, and don't touch me!" Renji warned her strictly.

Yuki Suou stuck out her tongue naughtily and leaned into his embrace. She didn't tell Renji. The reason why she wanted to help him pursue Yukinoshita Yukino was to gain the support of the Yukinoshita family.

After her brother was abandoned more than ten years ago, she lost hope in the Suou family. She also couldn't control her family alone. At best, she could become a tool for marriage. Even her future children would be fighting for the family.

Yuki Suou didn't want Renji to be controlled by others after returning to the Suou family. And the Yukinoshita family was the best choice.

"Brother, we won't have any more children," she suddenly said.

Renji's face was filled with confusion. "Why are you suddenly talking about children?" Why was this girl so random? What strange things was she thinking about.

Yuki Suou crossed her fingers, rubbed her cheek against Renji's chest, and said seriously, "Because if close relatives marry, there will be problems with the children!"

Renji immediately understood. This girl probably didn't know that he was adopted, and thought that he and Yuki were biological siblings. Renji had no intention of explaining. Instead, he asked naughtily, "What if we have a child?"

"Yuki, you know, your brother is very strong, and you are very cute. If that day comes, I won't be able to refuse."

Yuki Suou was very happy that Renji praised her like that and acknowledged her charm. So she said bravely, "If we have a child, just get rid of it! Solve the problem from the root!"

"As long as I have my brother's love, I don't need a child to steal my attention!"

Renji was surprised. "So cruel?" But he was also very touched. He didn't explain that he was an adopted child. Yuki was probably also immersed in the excitement of their "forbidden" relationship. So, it was better not to expose it.

He lowered his head and kissed Yuki's forehead. "Go to sleep. You have to go to school tomorrow."
