Not gonna lie, althought most of it's plot point are kinda of adult... Romance is a romance, and there's always the main character who's a fucking mental disabled dude. Like dude, how can you be "yes we are just friends, althought you actually confessed to me multiple times and cried like the last 3 times i saw you"
Don't get me wrong i really enjoy Haru chan and the whole story, but man... At times it can get so dumb with those type of things.
But i guess IRL romance is like that as well
