i just read the ending and i found it unsurprisingly disappointing. their make up was so half-assed and felt unfinished. also, haru forgiving kunihiko just because he said he liked him back rubbed me the wrong way. if kunihiko liked him that much, he should have confessed to haru instead of dating other people. their relationship might not be abusive but it's not healthy. healthy relationships should be give and take. haru is the only one giving in this, imo. all in all, it seems like haru is just settling for someone mediocre and ended up with kunihiko just because he's his assigned love interest and not because they have a strong connection.
i know we're meant to root for haru and kunihiko because they're the main couple but it's hard to do that (imo) when kunihiko doesn't seem like a reliable lover, let alone a goof friend. kuni has haru take care of him, he plays around with haru's feelings, and he messes around with other side chicks. to top it all off, he doesn't even have the balls to confess to haru and avoids him instead. haru needs a partner he can rely on, not someone to babysit.
