What Happened in Episode 1?
Welcome to Good Boy — where former Olympic heroes aren’t just saving medals anymore, they’re saving lives!
Yoon Dong-ju (Park Bo-gum), a disgraced boxing champ, finds himself in an unexpected career twist: joining the police force after his Olympic dreams crumble due to a doping scandal. But he’s not alone — he reunites with his former flame Ji Han-na (Kim So-hyun), now a skilled sharpshooter on the force.
Together with other ex-athletes, they form a quirky yet promising crime-fighting squad. Their first case? A wild pursuit of a masked criminal known as “Golden Bunny” that ends in an epic punch-out thanks to Dong-ju’s boxing chops!
It’s a mix of adrenaline, awkward reunions, and the bittersweet struggle of athletes trying to find new purpose.
Episode 2 Highlights: Second Chances & Suspicious Crimes
As the team settles into their new roles, things get serious. Go Man-sik, their tough-but-kind leader, proposes turning the group into a legit Special Crime Investigation Team. Sounds promising, right?
Well… turns out they’re mostly being used for media attention. Han-na isn’t having it and walks away — but not for long.
Meanwhile, Dong-ju uncovers the truth behind a hit-and-run case. His best friend is falsely accused, and the real culprit is hiding in plain sight. As Dong-ju digs deeper, we start to see the hero beneath the bruises.
