Forget Gwansik—Have You Ever Seen Park Bo-gum This Alpha?

Slated to take over the coveted time slot from Heavenly Ever After (which peaked at 8.3% in ratings), JTBC's upcoming drama is already generating massive buzz, especially because of Park Bo-gum's character.

Compared to his previous role as the sweet and tender Gwansik in Netflix’s When Life Gives You Tangerines, Park Bo-gum’s new character is gritty, macho, and reveals a bold new side of him that fans have never seen before.

Olympic Medalists Turned Cops in a High-Stakes Action-Comedy

Directed by Shim Na-yeon (Beyond Evil, The Good Bad Mother) and written by Lee Dae-il (Life on Mars, Chief of Staff), Good Boy follows a squad of former national athletes recruited as police officers through a special task force program. Swapping medals for badges, these elite ex-athletes now fight crime—and corruption—in a comic action thriller that dives deep into justice, teamwork, and second chances.

The “Goodvengers” Assemble: Cast and Characters

Park Bo-gum plays Yoon Dong-joo, a hot-blooded rookie cop and former Olympic boxing gold medalist. With lines like “The righteous will always catch the wicked—nothing is impossible,” Bo-gum’s explosive emotional acting and fight scenes in the teasers are already going viral.

Kim So-hyun stars as Ji Han-na, a calm, razor-sharp former shooting champion turned officer. Her quote, “Justice is on the side of truth,” sets the tone for her character’s quiet strength and precision.

Lee Sang-yi takes on the role of Kim Jong-hyun, a fencing silver medalist known for his unwavering pursuit of justice. His line—“Don’t even think about running!”—signals his intense, no-nonsense attitude.

Heo Sung-tae plays team leader Go Man-sik, a bronze medal-winning wrestler. His cold yet righteous worldview is captured in his line: “If you make others bleed, you’ll pay for it with blood.”

Tae Won-seok rounds out the team as Shin Jae-hong, a former discus medalist with few words but ironclad resolve: “Justice will be served.”

Together, they form the Goodvengers, a squad built on passion, pain, and purpose—each fighting for justice in their own way.

Anticipation Reaches Fever Pitch

The recently released “Fighting” version of the main poster shows the five leads in national athlete tracksuits, holding symbolic props: Bo-gum with a boxing belt, So-hyun with a rifle, Sang-yi with a fencing saber, Heo with a wrestler’s towel, and Tae with a discus—all poised for battle.

And the teaser? Instant hit. Fans are flooding online communities with comments like:

“Bo-gum’s acting is insane… Good Boy is my weekend plan.”

“This character might top even Taek and Crown Prince Lee Yeong!”

“Bo-gum + action + thriller + comedy? It’s over. I’m in.”

“Been waiting 2 years. Worth it.”
