Jae-Geun sexually assaults Yu-Ri in front of Su-Heon but he's too much of a cuck to intervene & stop him from raping his wife. lucky for Yu-Ri, May had stopped Jae-Geun from sticking his grossly big dick inside her.
Yu-Ri leaves her husband alone for days to be at her parent's home to clear her head. She had called Yu-Mi in advance to take care of him in the meantime. Su-Heon takes the opportunity to make advances on her.
