Hiii...Does anyone know a manga yaoi/shoujo/josei about a hate/love relationship?? but a reaal one..
Like, they really have reason to hate each other, they struggle but just can't resist.. or they really hate each other- but not really hahah sorry if it's a bit confusing, i'm not really good expressing myself!
