U and Bang chan knew each other since you were kids and eventually dated in high school. He was cold, distant, rude and flirtatious but he was nice to you. However, after graduation u broke up with him bcz you moved to another city. Now, you're 28 years old, walking through the aisle beside your fiancé. You're happy and waving and bowing through the crowd. But just then, your smile drops. You see bang chan, sitting in the corner with his legs crossed, drinking wine looking at you while smirking.
