You know why you felt like they had a proper communication but it feels like the seme is manipulating the situation?
It's because it's just words, anyone can say that. We need proof of actions. We need to see that seme is really sorry for what he did.
We are used to see in other stories that when theres misunderstanding, one of them will beg or even cry.
The facial expression is a big factor. When seme is explaining his side I don't see any regret in his face, so that's wy it doesn't feel genuine.
I'm not saying that he is not genuine but what he said doesnt convince me because of how they draw the situation.
