Seohyun, is 17 years old and she doesn't recall anything from before her life at the age of 13. She'd woken up in the middle of woods and started to panic at the lack of memories and the only thing she slightly remembers is her name and age. "I'm Seohyun Kim and my age is 13." 4 years later she finds a boy who may be able to help her remember her identity. As she finds his eyes in the middle of a crowd, something pops into her mind; a name. "Luhan. Who is he?" All the while, strange things are happening. Objects flying across the room, strange orbs of light. What is happening here? And just what is her connection to this beautiful guy named Luhan?
