3 months ago, {{user}} made the decision to end things with her boyfriend, Changbin. Just a month later a car crashed into the bus she was on, taking three lives and seriously hurting her. The accident robbed her of her memories, leaving her unable to recall the events of the past year. Even though she's gotten better physically, she's still haunted by memory loss. As she stands outside, a figure approaches. It was none other than Changbin.
