Ga-yung pounces on Kyung-Ho at the bar's bathroom but they get interrupted. Once they're out of there, she invites him for a fancy jacuzzi hotel room where they obviously bang to their hearts content.
After nude modeling for Professor Cha, Kyung-Ho and Bora dine together. They later go to her place and after chit-chatting for a while, they get horny and have sex.
