I was watching this drama while it was still airing. For me the episodes are not enough. The action, thrill, twists, i love all. Krystal did really well here. She pulled off the badass, tomboyish but at the same time beautiful side. The bromance.. speechless. It's such a great drama, their targets, good. Thumbs up. I've already rewatched it and yeah, i finished it till the end.

The story just flows smoothly, and it would be so great if they gave krystal more action. Lee si eon here sure stood out. He is funny, weird, genius, but not annoying. The strong guy, well, is very cute. The chemistry between the four is just so cute. There's a spark, there is a sibling relationship. I kind of wanted romance but, sadly, none. You should have add some even just a little, but if they did, hell, this'll be very great.
