The new K-drama Good Boy is already creating a buzz as it gets ready to hit JTBC screens on May 31, 2025. Packed with action, comedy, and emotional depth, this series brings something fresh to the table: a story about former athletes who swap medals for badges and step into the world of crime fighting.

At the center of it all is Park Bo-gum, who plays Yoon Dong-joo, a former Olympic boxing champ. Once the pride of the nation, Yoon’s life takes a different turn after a series of personal struggles. Now, he’s part of a special police unit that handles serious crimes. The ring may be gone, but his fighting spirit is still very much alive. His journey is all about finding new purpose and adjusting to a world where fists aren’t always the answer.

Kim So-hyun plays Ji Han-na, a former Olympic shooting gold medalist. Calm, sharp, and fiercely determined, she’s left her sports career behind after a painful incident and now wears the police uniform with pride. Her unmatched precision and cool-headedness make her a strong asset to the team, and her chemistry with Bo-gum’s character is something fans are looking forward to.

They’re not alone.

Additionally, the drama features a solid team of ex-athletes now working in law enforcement. Lee Sang-yi joins as a quick-thinking former fencer, Heo Sung-tae as a retired wrestler who now leads the unit, Tae Won-seok as a powerful ex-discus thrower, and Oh Jung-se as a customs officer whose polite exterior might be hiding something deeper. Together, they form a unit that’s as unusual as it is effective. Their different sports backgrounds give them unexpected strengths in the field.

Behind the scenes, Good Boy is in good hands. It’s written by Lee Dae-il, the mind behind Chief of Staff and Life on Mars, and directed by Shim Na-yeon, known for Beyond Evil and The Good Bad Mother. With this duo steering the ship, fans can expect a mix of tension, humor, and human moments that stick.

In addition, the show will air every Saturday and Sunday at 10:30 PM (KST) on JTBC. For viewers outside Korea, it’ll be available on Netflix, Disney+, and Amazon Prime Video, so international fans can keep up with the story as it unfolds.
