What happened in Good Boy Episode 12: A quick recap

Good Boy Episode 12 begins with a flashback of Jae-hong during his Olympic days as a discus thrower. It's heavily raining, but Jae-hong doesn't stop. He keeps trying despite the fouls, hoping to prove his skills one day.

The episode continues with the team carrying out its mission, being selfless. At the same time, Dong-ju is hiding his health crisis from everyone, including Han-na. When asked if his reports were normal, Dong-ju lied to her, but he won't be able to hide it for long.

As for Min Ju-yeong, his money may be gone, but that doesn’t mean he’s giving up. The criminal has been secretly selling Drug Demon’s candies to young adults to make some quick cash. Since Dong-ju has made things difficult for him, Ju-yeong has him attacked and injects him with a drug.

Dong-ju is brutally beaten, locked up, and taken away by Ju-yeong’s hitman. Despite his serious injuries, he somehow manages to escape. But now, he’s in critical condition, and on top of that, he’s being accused of a knife attack.


What to expect from Good Boy Episode 13?

The stakes are higher than ever as the team gears up to rejoin the fight and won’t back down until Min Ju-yeong’s criminal empire is completely taken down. On top of that, Drug Demon might actually side with Dong-ju now, since Ju-yeong betrayed her by selling the candies to kids and young adults, something she had clearly banned in their contract.

To make matters worse, the commissioner has now teamed up with Ju-yeong, which means things are only going to get harder for Man-sik and his allies. And as the preview shows, no one from the Insung Police Department seems willing to help him. That’s because Min Ju-yeong’s money is spreading like poison in the system, fast and everywhere.

So, don't miss out on the next episode on July 12, 2025.
