I remember reading this yaoi, the uke like admired the seme and like tried copying the seme's hair and clothing style because he thought he was so cool because he like got all the girls and stuff (but he was actually gay). I'm just annoyed I can't remember the title of the manga. I tried looking for it but nothing came up. I also remember the cover being like yellowish if that helps?

Aniki no Shigoki!
