perhaps huan wen snapped.. he's so mature for his age and he's right, even though i don't like red head that much uncle pan shouldn't toy with him, it's just immature when he's supposed to be the adult here..
it's so important that yuyang is thinking about the possibility of having arguments, there are always ups and downs in a relationship, that's totally normal.. he acknowledges his own flaws but also lihuan's bc he's sometimes too naive and has such a good temperament
