I can't say I didn't care for the story as I read all of it in one go and couldn't stop, but if I had to describe it, it was a grudge read. I only wanted to see how it ends. All of the male characters do not only have a flaw (flaws are what give us an actual plot), but I found them to be insufferable dolts bordering on being terrible human beings, which repulsed me.
Itta meets the girl he bullied years ago and expects her to jump for joy when he confesses his love for her, after continuing directly where he left off years ago by calling her names. If that is not wilful, he is years behind in his mental development. It is not until the sixth volume that he considers her feelings and background. He subjects her to this demeaning dating thing, expects her to 'come around eventually' (having no grounds to assume she would) and forces a kiss on her fully knowing she isn't attracted to males. Oh, and he stops her from going to look for Riri in the haunted house, which backfires terribly later on together with him not clarifying that the kiss wasn't consensual. I expected Fuuka to either stop the whole thing when it got too personal and retreat or get into a really, really bad fight (read: threaten on a personal level and then hurt) with Ikka, because that is what happens when people are pushed.
Actually, I have no clue why Ikka later decides to help them as he never seemed to frigging care. Then he says he has to leave for good and is suddenly back for good and presented as a guardian figure for the two.
And that strange sempai, who doesn't respect personal space and boundaries and finds it the logical thing to do when he gets rejected to out a gay couple. What a swell guy. I expected Fuuka to hit him with a chair and not apologize to that failure of a human being.
But maybe it's just me.
