Good Boy Episode 3 takes us in a more emotional and serious direction — but somewhere along the way, the charm we saw in the earlier episodes begins to fade. The story tries to juggle too many genres and ends up feeling a bit all over the place.

Good Boy Episode 3 Recap
Good Boy Episode 3 opens with Han-na’s flashback, where she’s just about to make history at a championship — until her hair suddenly comes undone, distracting her at the worst moment. It’s a small but powerful scene that shows how fragile her dream really was.
Meanwhile, Dong-ju spots Ju-young at the customs office and immediately causes a scene. He’s convinced Ju-young is the man behind the hit-and-run case, but of course, without evidence, no one listens. Jong-hyeon then enters the picture and challenges Dong-ju to a sparring match — and surprisingly, wins. Turns out, he’s been doing Taekwondo since he was a kid.

News of Gyeong-il’s arrest breaks, and Dong-ju goes to visit his mother, who still believes the truth will come out. This motivates Dong-ju to start digging into the car Ju-young was using that night. But then comes a shocking twist — Gyeong-il dies in prison, and it’s clearly been staged to look like suicide. A prison guard’s watch is found at the scene, and things start to get messy.
Devastated and angry, Dong-ju lashes out and attacks Ju-young. He refuses to be manipulated anymore. At the same time, Han-na finds a similar watch in her father’s things, which leads her to a pawn shop. There, she learns the watch is a rare edition used by smugglers. Suspicious? Definitely.
Ju-young realises someone’s been snooping and starts suspecting Han-na. We also get a bit of backstory: Gyeong-il was never Dong-ju’s brother, just an old competitor from his fighting days. Still, the guilt hits hard.
Good Boy Episode 3 Review: Kim So-hyun
Back home, Han-na finds out her mother has secretly put their house on the market to pay off debt. She also realises that on the day of her big championship loss, her mom was too busy working on advertisements to help her — and that moment stuck with her. On top of everything else, Han-na collapses outside the station due to an ongoing illness. Dong-Ju is there, and he catches her just in time.
Jong-hyeon starts digging and finds out someone has been looking into Han-na at the station, which raises even more red flags. Han-na gives Dong-ju back his old medal, and in return, he decides to keep working on the book he owes Ju-young — but it’s clear he’s planning something else.
In the end, Dong-ju breaks into the customs office and boldly warns Ju-young that he’s coming for him. And just like that, the episode closes on a tense note.
Good Boy Episode 3 Review
Honestly, Episode 3 felt a bit messy. The show is trying to do a lot — crime thriller, emotional backstory, action, mystery, even a little romance — and it’s strating to lose focus. The plot jumps around so much that it’s hard to stay invested in every storyline.

Dong-ju continues to be the strongest character. Park Bo-gum really brings intensity to his role, and his scenes are always watchable. But the rest of the characters, especially Han-na and Jong-hyeon, still don’t feel fully developed. We get glimpses of their past and pain, but the show doesn’t spend enough time letting those moments sink in.
Even Gyeong-il’s death, which should’ve hit us hard, didn’t have the emotional weight it deserved. Everything moves too fast for us to really connect.That said, the mystery around Ju-young is heating up, and the confrontation between him and Dong-ju adds tension. I just wish the story was more cohesive. Right now, it feels like several different dramas mashed together.
Final Thoughts
Good Boy started strong—with fun action, great chemistry, and a fresh vibe. But Episode 3 starts to show cracks. The pacing is off, the tone feels inconsistent, and the emotional beats don’t always land. Still, someting is compelling about Dong-ju’s determination and Ju-young’s cold, villainous presence that makes you want to see what happens next.
