Of course he will not "cheat on" Nemu on purpose but because of his lack of awareness. I'm sure he's gonna tell Nemu that it's ok to work with Ruka. He'll spend a lot of his time with him which is gonna make Nemu insecure. Nemu will tell Maya to be "careful". He's gonna be pissed because "you don't trust me ? I told you Ruka is a good guy ! Stop spreading nonsense". And Ruka's gonna still a kiss from Maya. With the "no lie between us", Maya will tell the truth to Nemu and "broke up" because "I'm in wrong, I'm not good enough for you. I always make you suffer" blablablabla ╥﹏╥
(sorry for my bad english)

If the one breaking up is Maya I would be even more pissed,cause I know for sure that in that case it will be Nemu AGAIN the one chasing after him. And I hate it when the person who did nothing wrong is the one fighting to keep a relationship.
Maya should beg for forgiveness (if what you said happens) and Nemu should stay mad for a long time. That'll be fair

And I think it wouldn't be Maya's fault if Ruka would kiss him... Yes he shouldn't lie about the fact that he spent night at Ruka's place but we can't blame him for trusting in his friend. As far as the story is now Ruka didn't do anything that weird with Maya (nothing that friend would do) we see the story from Nemu and also Ruka's PV so we know he's planning something bad but Maya doesn't know that so it's not his fault.
I also think Nemu is right to be jealous because he see that Ruka is acting in a weird way so he can sense that something is wrong but Nemu never told Maya about that so Maya just thinks that Nemu is jealous because he's spending too much time with Ruka and because of Nemu's low self-esteem so... to sum it up : I think it's worse to lie to your boyfriend than to be kissed against your own will by someone you trusted...

Do you guys remember Maya's reaction when Naoya kissed Nemu? Grabbing Nemu, scaring him while yelling in the middle of the street "I told you!! You should have taken more care!! I said that you couldn't trust in that person". That is, he is the right to reproach Nemu every single thing he wants, BUT when it's Nemu the one asking for an explanation he doesn't deserve it cause he's imagining things and acting like a drama queen. Kiss my ass, Maya .l.

Yeah well but that would make Maya a victim and even if he's not perfect and I'm angry at him I hope he won't get rape (even tho he did the same with Nemu at first ugh)
Ruka is f up so I also think he could do that... I just hope Maya will realise it soon before something really bad happen... rape would be even worse tham Maya cheating. I don't want any of that

Lmao. Did you read the earlier volumes recently? Maya looked like he just got out of juvie. He damn near scared Nemu's mom to death when they first met. She had to question Nemu's life decisions and everything after he brought Maya around. There's no denying that his look changed a lot. He really cleaned up.
If Maya cheats on Nemu and sleeps with someone else I swear I drop the manga and throw my hard copies into the trash can.
