Despite having to struggle every day just to scrape by, Taemin never lost hope that one day his life will get better. Unfortunately, this was just a pipe dream because he ends up getting into a car accident and waking up in the hospital as Han Siwon, a victim of bullying. He soon finds out that although it appeared Siwon had everything one could ever ask for, his life was much darker beneath the surface. To make things even more complicated, Min Woojin, an old friend from Taemin’s past, somehow has something to do with Siwon ending up in the hospital.
