Hostile Relations

My childhood friend from abroad is back, the bastard who always outdid me at everything when we were kids! Zhou Yuan thinks to himself: You're finally back. Just wait, I'm going to bully you to death! Everyone: ...Why aren't they acting like childhood friends are supposed to? Huh...? Why isn't this going the way I imagined? Why did he somehow become my deskmate and move into my house? Even though I can't stand it, I still lose to his top-student aura. Zhou Yuan: "Big brother, can you do my homework for me?" Hearing him say "big brother," Cheng Jinfan gives him a smile that's hard to read. "Sure. I'll do it for you." At that moment, Zhou Yuan is happily playing video games, with no idea how badly his so-called "big brother" will bully him in the future. Theme: A youth spent walking toward the sun.
