Great K-dramas often have a secret ingredient: a cast that genuinely enjoys each other. Dive into You just released a making-of video for episodes 3 and 4, and it suggests this team has plenty of it. There are emotional scenes, comic chaos and even a karaoke session.

Dive Into You: Behind-the-Scenes Highlights

Actor	Moment	What It Shows
Kim Ji Yeon	Kept crying after a take ended	Deeply immersed in a difficult scene
Jang Se Hyuk	Chaotic action scene	Pure comic energy that left co-stars laughing
Park Seo Ham	Teamed up with Kim Ji Yeon for action	Impressive, in-sync stunt work
Kim Ji Yeon	Showed off her judo uniform	A playful nod to an earlier role
Whole cast	Karaoke session	Great vocals and a relaxed, fun mood

From Serious Scenes to Big Laughs

The video opens with Kim Ji Yeon, Park Seo Ham and Jang Se Hyuk rehearsing a tough scene. Kim Ji Yeon gets so absorbed that she keeps crying even after the camera stops, the kind of commitment that usually translates into a powerful moment on screen.

Then the mood flips. In an action scene, Jang Se Hyuk’s chaotic performance has both of his co-stars struggling to stay serious. The two women still manage to team up for an impressive action sequence of their own, which is a nice reminder that this cast can switch between comedy and intensity quickly, according to Soompi’s report.

The Judo Connection

Park Seo Ham says it was hard to keep from laughing, but she finds Jang Se Hyuk’s character, Ha Ru, charming. Since Ha Ru has a judo background, she says she leans on him during filming.

Kim Ji Yeon joins the fun by showing off her judo uniform and joking about being a national team member in her “past life.” That’s a wink at her character in Twenty-Five Twenty-One, and fans of that drama will appreciate the callback.

Karaoke Night

The video ends on a high note, with the cast singing freely and impressing everyone with their vocals. Moments like this show the warm chemistry that often makes a drama feel special to watch.
