I think kaname is just a dense, naive anf a guy who can't express himself that's why it looked like he forced the uke at chap 1 to sleep eventhough the uke didnt really enjoy it. I think he didnt know about that, that's why he tried to do research to please the uke
hahaha i tried not to cry but i'm crying like a kid now. i just started to simp him and then the ending killed me
