Red hair is too emotionally dependant. The blue hair's character settings follows an overused troupe that it's hard to tell him apart nor sympathize. I mean, I'm even more interested by the red hair's otaku ish roommate than the romance between the main couple. It's really cliché. Oh but of course the uniue twists could be attractive to other readers, have fun.
Boy1 and boy are in a art college, they fell in love and date. Boy's1 parents are abusive and don't want him to pursue the art path and so they would beat him up and lock him in the house, boy2 helped him escape that. Then there's a LOT of unnecessary drama. In the end they are happy together.
