But he does not know GM has any connection to Miju (and to him, the only connection SM has is that he possibly helped get rid of her on his father's orders).


Ah. I'm watching those episodes RAW, so I thought it had been mentioned. This way, it does kind of make sense that MW would no longer trust SM and may even shoot him at a later date. Still, I cannot see MW hurting anyone outside of business, simply because of the mess that happened with Gangmo.
