Hyeon will be leaving far away, maybe abroad? or something - living an independent life.
Hyeon's brother is now the CEO, and I think on a friendly-somewhat relationship now with Hyeon (last scene where he says sorry and he was asking if Hyeon will really be leaving)
Dr. Baek stopped his fetish(?) orgy activity (his phone scene with his previous partner (i supposed the blonde guy).
His college friend still looks for Hyeon. This was a bit sad bcs Hyeon rejected his friend so that he will not hurt him any more than that.
So the dad resigned but the whereabouts are unknown but I think he was arrested (remember the scene where Dr. Baek and Hyeon is having their session with a recorder on, where hyeon spilled everything. After that, the brother thanked Hyeon - denoting that they have now the evidence against the father. we all know that the hyung also hates their father)
Overall, this was a decent and realistic ending where there's no really a happy or sad ending. It's just - life goes on.
So cute (ノ≧∇≦)ノ ミ ┻━┻
