So ep 16 was the beginning of YH fall out with TY. It was a straight out misunderstanding. TY did not even bother to explain first and just went with the stab. So it was pain and the dark aura that has been bestowed to YH that will lead to the scene where YH was walking away from TY saying she did love him once.
Can I just say Zhou Shen's song is such an ear candy. I played it on loop. And I never get tired if listening. Really something. Like his OST for Lighter and Princess
