I haven’t actually read it yet but it suits the description of the cover. I had read something like this a long time ago but I’m still looking..
YEEEEES IT'S THAT(≧∀≦Thank you very much
I remember reading something that was about a sort of love triangle : a guy who loved a girl, but the girl was in love with the guy’s friend, and this one was in love with the guy (they were high school students). So the guy was helping the girl seduce his friend although he was in love with her, but she ended up going out with the guy.
The story wasn’t finished, and it was a manga.
There was also the girl’s best friend, who was in love with her (so she was in the same situation of the guy’s friend), who hated the guy or his friend (I don’t really remember which one of them)...
The title was something with « blue » or « sky », if I remember correctly... The cover of the first book showed a high school , the three members of the love triangle, they were outside, the sky was blue and there were trees...
