Ohhhh I don't think he betrayed him, it was more like "it's forbidden for us to love each other" which is what chagang had stuck in his head which made him push moonhyuk away, plus it was dangerous because of scarface as chagang was Scarface's dog. And scarface for some reason, I honestly don't know how or what he thinks but I think we'll find out the reason why he got him killed. And if anything, it was chagangs other right hand man that betrayed both of them by teaming up with scarface and that's what got chagang killed. Man, normally I don't like a former lover but in this case it actually saddened me that he died because of how much moonhyuk loved him but I still prefer yeonjin.
Any theories of why he betrayed moonhyuk?
I honestly think he wanted to protect him
