yeah, i agree but also, while maya has obviously grown up from how he used to be, i still think he doesn't always understand nemu. which is understandable, but he probably should have known just from nemu's personality, that he would be worried if maya snuck off in the middle of the night, and proceeded to lie about where he had gone. which makes it into a big deal when it really wasn't.
I think at this point, Maya isn't considering Nemu's personality and how to maturely and respectfully confront their conflicts as much as he's worried about how to "deal" with Nemu. Easier to try to hide things he knows might upset Nemu than to have a (possibly uncomfortable) conversation about it. The former takes more work, but it's essential for a strong long-term relationship. Hopefully, they get there in the end.
It's clear to me that Nemu sees himself as the less desirable of the pair--as the one who has more to lose--and this hinders him from asserting his needs with too much fervor. He might get angry with Maya but it's never for long, and I'm concerned Maya isn't really learning anything from these brief exchanges.
It's painful to witness. Nemu as the one who sees himself as less attractive, less personable, who is less experienced and--let's not forget--was raped by Maya at the onset of everything. I don't think Maya means to be malicious towards him, but their relationship imbalance isn't healthy and it's going to combust if something (someone...) doesn't change.
