I agree. Super lovers is one of my favourite mangas and I buy the quarterly releases as well so I'm not just some random hater, but Haru is definitely toying with Ren's feelings even if it's unintentionally at this point. I know they both have their own issues but Ren really only has eyes for Haru, so I'm a bit frustrated by Haru treating Ren like that, taking him for granted :(
I think the imprinting aspect really bothers him that's why he won't make a move. He may doubt that Ren's love is the same because he is naive
Totally selfish
Im starting to get pissed by haru, insensitive, selfish and acts like he doesnt know what ren feels about him (somwtimes). And no ones gonna believe in you in a excuse of "too young to do it" if you already touching him doing pervy stuff, that resolve is weak, dont touch ren at all if you gonna use that excuse!
