"DoN't ThInK ThAt I'vE aPpRoVeD oF YoU!" motherfucker, what are you, her dad? what the fuck you mean? you never had any claim whatsoever with who she has a relationship with, and she already rejected you. move the fuck on, you denser-than-a-black-hole idiot! i'd expect this much denseness from a harem protag, not from a secondary character...
Well I first reread the manga. Yeah sure it's ok. The art is subpar (not that I can draw even if my life depended on it). Story is....meh same old same old.

That guy gives of stalker vibes. He's a creep. She already said multiple time to bugger off and he's still going for it. How dence can you get? (Or more precise, obsessive)
