Jung Joon Won, an actor, was interviewed by iMBC in Gangnam, Seoul, to discuss the conclusion of 'Resident Playbook', a TVN weekend drama that is a spin-off of 'Hospital Playlist'. The show narrates the journey of medical residents at Yulje Hospital in Jongno as they experience denial, growth, and acceptance on their path to becoming doctors.

In the drama, Jung portrayed Koo Do Won, a fourth-year OB-GYN resident. His character's romantic storyline with Oh Yi Young, played by Go Youn Jung, resonated with the audience. Jung expressed surprise at the overwhelming love for the 'Okoo couple', as he had expected the focus to be more on the residents' development rather than their relationship.

Initially apprehensive about his on-screen chemistry with Go Youn Jung, Jung aimed to portray his character realistically, despite the idealized nature of Koo Do Won. He worked to bridge the age gap with his co-stars, fostering a comfortable and friendly atmosphere on set.

The drama's success significantly boosted Jung's popularity, reflected in his rapidly growing Instagram following. He humorously mentioned checking his follower count daily with joy. Jung closely observed viewer feedback, noting the shift from mixed responses to growing acceptance of his character.

Acknowledging Go Youn Jung's beauty and the unrealistic aspect of their characters' romance, Jung appreciated the initial skepticism from the audience. While joking about his efforts on appearance, he emphasized his focus on delivering a strong performance. He expressed gratitude towards Go Youn Jung for her exceptional acting, which helped sway viewers who initially had doubts.

The final episode of 'Resident Playbook', led by Go Youn Jung, aired on May 18th, concluding the series.
