Though there's nothing new to the plot; the story is well-written and not boring for a second. The twist is so interesting and the freaking comedy at the beginning is insane. This is the last work of Cha Seung Won I could find online; and my 21st; and I can assure you his performance here is outstanding. I cannot but bow in respect. Apart from the ending track I can't recollect any music. The track made up for that though. I can see myself watching this again and I'm sure I'll enjoy it even better.
