If you are planning to watch it because of Song JiHyo, go ahead because same I watched this because of her. The movie was great, it started out with some back story regarding the whole movie it was great. SeoJin (Mooyul) was trying to find his sister then Yoojin (Jihyo) came at the right time then you are not expecting on what will happen next! The whole movie was a roller coaster ride! So many things happened that left me speechless. I enjoyed watching it so i feel like you will too! If you finished watching this, and you want a similar story, I suggest you watch “Save me” “구해줘” the story is similar.
