cannot STAND naru

I wouldn't have even bothered to comment this until I found out that naru had his own story with FOUR(!!!) volumes and not only that his love interest is a family member who's 25 years younger than him??? I don't mind age gap at all, and I don't really mind (non blood related) family stuff but those factors combined with the character I already know as Naru is so frustrating cuz I just wish Love Nest had that many volumes (or even more of masatos kouhais) and I'm mad he got to have that many
I have never liked Naru in the prev stories and I have always thought that his behaviour was so snakey and makes for an awful friend but because the plot allows for it, everyone around him believes his actions to be reasonable?? I genuinely believe his behaviour is EXACTLY the same as Masato's old habit for homewrecking (just less hands-on) and Masato pays the price for his past mistakes (which I don't even think are that egregious) but Naru's actions are viewed as saintly because it helps in the end. But all he does is also meddle in others relationships, mislead everyone, cause misunderstandings, omit key information, and set up the situations to turn out in such ways. + basically assaulting Masato twice just makes him a creep overall. I just can't stand him and I'm jealous he gets his own story with so many volumes (︶︿︶)＝凸
