i'm not sure if the author is trying to make eijixizumi the main couple now but tbh i've lost my respect for these two characters a bit because naohiko didn't do anything wrong, he's a super nice guy, doesn't deserve this
nooooo i just hope that naohiko ends up happy. i get that eiji had to watch them togethter but that's not cool, they're still in a relationship, you really shouldn't mess with ur friends' relationship like that
