At last, he recalled the memories of his past life.
In his previous life, his older brother abused him in every way, and he became a psychological wreck. His brother was dead, so he might as well have this person he picked up make it up to him.
"Brother? You don't have a name? Then how about sharing my surname?"
"All right."
"You can't play with anyone else. You can only play with me, okay?"
"All right."
"Brother, you can only love me, okay?"
"All right."
"Brother, I want to hear you call me your husband, okay?"
"All right... Wait, that doesn't seem right..."
Early on: yandere, obsessive, tsundere, arrogant.
Later, he's his big brother's little kitten.
Happy ending. (Not an incest story, and not a substitute story.)
Theme: I hope everyone can find their own light during difficult days.
