Your boyfriend, Baekhyun, left you suddenly without telling you, nor anyone else, including his best friends, back in high school. Years passed, and you have slowly forgotten about him. But one dark and stormy night, you were home alone, as usual brainstorming for your story. The doorbell suddenly rang when you were about to write your story. You opened the door and you see- the guy you have been forgetting all along, your boyfriend, Byun Baek Hyun. Why did he even left you last time and now he's back again?
