GOOD main leads.
GOOD plot.
Above-average supporting characters.
An over-drag villain.
A complete disastrous representation of SK law.
A little bit of disappointment in the ending.
Overall a good watch.
A big no for re-watch.

The story begins kinda slowly. But after episode 4 it picks up the pace and makes you believe that our star MC will fight the evil and get his girl for sure. Slowly the plot twists arise and the episodes became more of an action-comedy to me. The execution of Gangster vibes is in check and the cuteness of Jeon Yeo-been makes your heart go throb.
If you like mafia / gangster type revenge plot with rom-com GO for this.
