First, it was short and action packed, so it kept me engaged until the end. The acting was amazing, characters were interesting and the music was a bop, I could have finished it in one day, but because of work I finished it in two! I truly recommend it but some things don't add up (SPOLERS!!!):



Why didn't the police protect Jiwoo in any way? That captain knew what was going on but did nothing... I suppose he thought she died as well, but he could have found her before that whole ordeal happened and protect her in some way.
If he wanted to keep her busy and also protect himself, Moojin could have fabricated some evidence to make her suspect the captain. Why didn't he just kill Gangjae instead of only hurting him? That guy was crazy, it was obvious he would try and get revenge?
And soo soo many other stuff... like how did she even survive at the end? Who helped her? The captain? The police was searching for her, how didn't she end up in jail?

I was so invested in this story it was hard to question things while watching it, only after so it was really good anyway!
