Resident Playbook Just Got a Lot More Interesting — A Surprise Actor Has Entered the Scene

Jung Kyung-ho is officially making his return as Kim Jun-wan, the blunt but beloved cardiothoracic surgeon, in episode 4 of tvN’s weekend drama “Resident Playbook” (also known as Wise Resident Life), airing at 9:20 PM on April 20.

In this episode, Kim Jun-wan — now the head of cardiothoracic surgery at Yulje University Hospital — makes a surprise appearance in the obstetrics and gynecology department at the Jongno branch of Yulje. Fans can expect to see his signature charm: tough on the outside, soft on the inside.

In episode 4 of Resident Playbook, Go Youn-jung’s character, a resident OB-GYN, leaves a strikingly negative first impression on Professor Kim Jun-wan (played by Jung Kyung-ho) during their unexpected encounter. When Jun-wan visits the Jongno branch’s OB-GYN department, he witnesses her dealing with a patient in a way that comes off as curt and emotionally detached. Her cold, no-nonsense demeanor clashes with his expectations, sparking immediate tension. Though brief, the scene sets the stage for potential friction — or growth — between the two characters moving forward.

Throughout the remaining episode, Go Youn-jung’s character gathers the courage to approach her crush, Jung Joon-won’s character, in a sweet yet awkward attempt to get closer. Despite her subtle efforts and visible nervousness, the interaction doesn’t go as smoothly as she hoped. The moment is filled with quiet tension, missed signals, and endearing vulnerability, capturing the realistic struggles of one-sided affection and the difficulty of making the first move in a professional setting.

Earlier in the series, Ahn Eun-jin (as Choo Min-ha) made a striking first appearance, kicking off the expansion of the beloved Hospital Playlist universe. With the return of familiar faces from the original “99s” crew teased, anticipation among viewers continues to rise.

In newly released stills, Jun-wan’s visit to the Jongno branch has sparked curiosity. Why would a doctor from the main Yulje Hospital show up at a different location? The mystery has fans buzzing with theories.

This marks the first appearance of a 99s member in Resident Playbook, and fans are eager to see how Jung Kyung-ho’s character fits into the new storyline. Creator Shin Won-ho previously expressed deep gratitude at the press conference, saying, “I’m so thankful he treated this project like his own.” With that heartfelt connection behind the scenes, all eyes are on what kind of impact Kim Jun-wan will have this time around.
