That is what happens to So Mun one day when he gets possessed by a spirit. Well, that is kinda what happens, turns out you only get to keep the superpowers you get if you use them for good, aka hunting down evil spirits and making sure they don't go around hurt and killing people

This is such a good drama that keeps the momentum from the first episode going all up until the last one, it is a fun ride with plenty of emotional moments that didn't fail to get my eyes all misty.

This is one drama I'd recommend everyone to watch since it has a little bit of everything. Great stuff!
