[All] Good Boy 1st teaser video released! I'm so excited

The first teaser video is a rhythmic development that goes back and forth between melodrama, comedy, and action, and is the birth of a new youth hero story.

Good Avengers' Park Bo-gum, Kim So-hyun, Lee Sang-yi, Heo Sung-tae, and Tae Won-seok's unstoppable cider run

I'm really looking forward to it after watching the teaser video hehe

I just want to see it sooner! Haha
