While others are thinking Attorney would kill the cousin, I just feel like he won't dirty his hands for Kiseong. He did it with the mother last time but it was for KIJEONG which makes sense coz she's the one he's after. So from that moment in the convenience store, I was thinking he's still after Kiseong's suicide and iusing the cousin to drive him crazy is his move.
