Fans of the “Hospital Playlist” universe, get ready for a dose of nostalgia!
Yoo Yeon Seok is officially set to reprise his beloved role as Ahn Jung Won in the next episode of tvN’s “Resident Playbook.”

The drama, a spin-off following the everyday lives, struggles, and friendships of young residents at Yulje Medical Center’s Jongro branch, has already captured hearts—and now it’s bringing back a familiar face from the original series.

🌟 Ahn Jung Won Drops In

The Resident Playbook production team confirmed on April 26 that Yoo Yeon Seok will appear in the fifth episode, following the recent cameo of his Hospital Playlist co-star Jung Kyung Ho.

In newly revealed stills, Ahn Jung Won is spotted attending a team dinner for the obstetrics and gynecology department—not his usual pediatrics team—at the Jongro branch. His unexpected presence has left viewers buzzing:

• Why is Jung Won mingling with doctors from a different specialty at a different hospital branch?
• Could this be a hint at deeper connections between the Jongro and main branches of Yulje Medical Center?

No matter the reason, one thing’s for sure: seeing Yoo Yeon Seok as the warm, kind-hearted doctor again will surely be a highlight for longtime fans.
