I Can Never See Siblings in My Life [Tutor]

When I was four years old, I was taken home by Uncle Yamamoto. He gently held my shoulders and looked at me like a dead comrade resurrected in another form. He said, "Xiao Wei, this is your home from now on." My uncle has a son who is two months younger than me. Naturally, Yamamoto Takeshi and I, the boy who smiled stupidly when he saw me and always followed me step by step, became nominal siblings. When I was fourteen, my biological mother showed up.

Until the age of twenty-four. I opened my eyes after being hungover, turned around and saw the peaceful sleeping face of the half-naked man beside the pillow. He was silent for two seconds. When he came to his senses, Takeshi Yamamoto was already covering his face and said in confusion that it hurt. But my palms hurt even more. I asked, why are you at my house? He was startled, as if he didn't understand why I asked, and then smiled at me like he did when he was a child. This former good brother said, we are originally a family, sister. At this moment, I suddenly thought to myself: The sister-brother line of the otome game I bought last week is definitely unplayable. - 1. IF line imagination 2. The character of the protagonist is the same as in the previous book. He looks like a genius who strives to be excellent and perfect, but in fact he is a nerd. But since childhood, only Yamamoto has known his true side. Mission: No pain, no gain
