James walks out of his class and he doesn't know what in the world just happened back in class.
There may be a bit of regret seeping into him but he's kind of trying to ignore that because it's not happening well to him.
He doesn't understand why he had yelled at Lia in a way that he doesn't like as he's trying to think back on it.
There had been something in the way his heart felt like it was being lit ablaze when he had seen Lia having a conversation with the guy and it's not that it was the main concern of him but the fact that Lia had left behind his lecture and was rather chatting with whoever this man was what made him flare with the anger that built up inside him.
James is aware of the fact that he's in no way allowed to do that but it's one of those things he doesn't seem to have control over.
Although there's guilt in him and that's not a feeling he's used to.
