I mean, what they do in their relationship is their business after all. XD No need to wrap your head around it if it isn’t to your preference. For example, I can’t imagine myself having sexual relationships because I’m asexual, but I know people do it and as you’ve said, I respect their choices on the matter. u:
I am VERY CRITICAL about polyamory in fiction. This one is just friends being very casual about sex. They don't love each other equally, there's an imbalance. Even Nao has a girlfriend he supposedly loves? I mean, if you're having sex with dudes more than your supposed girlfriend then you need to re-evaluate your priorities.
