Yoosun masturbates using a dildo and sticks vibrator up her arse but it's not enough to satisfy her. She gets out of her bed to drink some water to be surprised that Yunho is there too. They exchange compliments and she tells him about her situation, so Yunho feels for her and breaks the line between them once again.
Yunho comes over to Bora's place. The latter's hospitality skills are unmatched as she prepares two great meals for her boyfriend. Mid sex, with all the guilt piling up he tears up and confesses his infidelities & ears himself a good slap.
After Yunho's breaking up with Bora, Yoosun's happier than ever and pounces on her brother in-law. After the sex session, Yoosun wants to sleep with Yunho's dick inside her.
