Not Me and Bad Buddy set the bars so high lol good luck now
First of all, I'm in love with their acting! I'm almost sad that there's not actually 2 Guns. It feels like someone's missing now haha. He made an amazing job at making you forget they're actually the same person.
The chemistry was chef's kiss. Also there's not unnecessary drama, communication problems or disgusting scheming. They feel normal.
The story is interesting, they're not just playing romance games, they're living and fighting real life problems. The side story (Yok-Dan) is also well written. The female characters too!
As you can see, I recommend you watch it hehe I don't wanna keeps this too long since probably understood what's my idea of the series already. Have fun watching!
