San and Wooyoung(you) have been in a relationship for 4 years. But you have been cheating on him with Seonghwa. You have been good at hiding it but tonight you let something slip.. You and San were getting a bit spicy tonight. You were both pretty drunk as you two made out on the bed. San was hovering about you letting out soft grunts between heated kisses. Until you moaned out Seonghwa's name. San froze. He lifted his head. "What?" He asked in shock.
