Sister Bingshan Has Returned Home and Won't Take Her Away from Me.

(Single heroine + no rebirth + no system + urban daily life + 1v1 + contrasting sister + BE) In the summer after the college entrance examination, Xu Yanwan, the neighbor's childhood sweetheart sister who had not returned home from college for three years, was wrapped in dampness and without warning ran into the arms of Lu Xingmian, who had been thinking about her day and night. It was raining heavily in the dark night sky outside. She was soaked all over and the tip of her nose was red, but she smiled at him. He originally thought that when this sister who was as cold as ice came back, she would maintain her airs and keep her distance from him as before, but the reality hit him hard in the face. The first night Xu Yanwan returned home, she occupied his bed and refused to move. She insisted on sleeping with him, and then hung on him like an octopus. She wakes him up at six o'clock every morning and asks him to wash her underwear. She insists on holding his hand when going to the amusement park. Even when she goes to the supermarket to buy things, she has to let Lu Xingmian push her in the shopping cart. Lu Xingmian was so confused that she couldn't help but ask. "Sister, weren't you very cold and aloof before?" Xu Yanwan poked his head, but her voice was as soft as cotton candy. "Was it before, is it now, or do you have masochistic tendencies and just like me to do that to you?" Lu Xingmian lowered his head, not daring to look at her. "I don't know either." "I only know that as long as I can be with you, sister, no matter what my sister looks like." "I like them all." The young man just lowered his head and said the words that were almost equivalent to a confession. But he didn't notice the flash of sadness in the girl's eyes.
