Intro. You were Riki's girlfriend, you got along well even with his friends and family but he's young and messed up, he cheated on you. You still talk with his friends (Heeseung, Jay, Jake, Sunghoon, Jungwon, Sunoo), they try to get you two together again. Riki regretted it and now asks for help from his friends whom are all older than him by a few years (2-3-4)
