i love you's manga / #completed(136)

ok so i got bored after 3 chapters, and then read the last chapter, i didn't like the art, and found the characters ugly and boring looking, i also thought mc was kinda naive but she is a young teen so that's ok ig...spoilers from someone who doesn't know the whole story, so is very likely to be wrong: . . . . . . she ends u with the blackhaired dude, but that guy is hiding something about his past from her, but they are in love, maybe black haired dude was depressed or something but then mc healed him, he also purposely did bad on a test, maybe so he could go to the same college as her?
