Nam-Wook takes Ga-yung with him to an empty classroom (it's not empty) and fucks her really close to the locker where the Kyung-Ho & Seung-Ah were hiding.
Hye-sun wants to end her sexual relationship with Jung-hoo but he gets a boner after hugging her. Now he wants to fuck her so bad and starts to force himself on her. Ajumma stops him from groping her and gives him what he wants but it's the last time she's giving him a favor.
