When I first started watching this drama, I had no expectations. After countless fluffy romcoms, I was craving something different. I'm thrilled with my pick because this series brilliantly blends the best elements of Hong Kong gangster movies from the '80s to the 2000s within a unique Korean K-drama framework.

Set in the '90s, the show brings a wave of nostalgia. The era's charm comes alive with slightly oversized suits, chunky Mercedes S-Class cars, and the iconic Motorola StarTAC flip phones. It's just delightful.

This drama borrows a lot from Hong Kong gangster films. The main characters remind me of those in the 2002 film "Internal Affairs," where the protagonist pretends to be a gangster while actually working undercover as a cop. But the series takes that inspiration and makes it its own, with a distinctive style and story that keeps you hooked from start to finish.

Ji Chang Wook totally shines in this series. He nails the double agent character, making you feel every emotion and frustration he goes through. His fight scenes are spot-on, though some are so intense and violent that I had to look away.

The rest of the cast is great too, but I was especially impressed with Bibi. I'd never seen her work or even heard of her before this. I was shocked to find out she's actually a rapper, singer, and songwriter. Her portrayal of the daughter of a Mainland China gangster was so convincing it's hard to believe she's not a full-time actress.

With only 12 episodes, the drama moves at a good pace without any unnecessary fillers. I highly recommend it to anyone into crime thrillers or just looking for a change like I was.
