CNBLUE’s Lee Jung Shin Trades His Guitar for a Stethoscope in New K-Drama

Musician-turned-actor Lee Jung Shin is adding another role to his growing acting résumé. On August 14, it was officially confirmed that the CNBLUE bassist will join the cast of MBN’s upcoming romance drama What a Boss Wants, stepping into a role that’s about as far from rockstar as it gets.

What’s the Drama About?

Based on a popular web novel of the same name, What a Boss Wants follows Kwon Do Hyuk, a chaebol boss with famously terrible taste who becomes obsessed with tracking down a mysterious woman after hearing her voice on an album. That woman turns out to be Lee Eun Chae, the lead vocalist of an indie band, who quickly becomes the one unpredictable variable in his otherwise flawlessly controlled life. It’s a classic “opposites collide” romance premise, wrapped in music and unexpected chemistry.

Lee Jung Shin steps into the role of Moon Tae Kyung — a pediatrician who seemingly has it all: good looks, a warm personality, and a privileged family background. As a supporting lead, his character is set up to add complexity to the central romance, likely as a compelling third point in the story’s emotional dynamics.

Why This Casting Matters

Lee Jung Shin has steadily built his acting credentials outside of CNBLUE, most recently starring in Summer Guys. His addition alongside previously confirmed leads Sung Hoon and Oh Se Young rounds out a cast that blends established acting talent with idol-actor crossover appeal — a combination that’s often proven successful for MBN dramas aiming for broad audience reach.

With a November premiere still months away, fans have plenty of time to catch up on Lee Jung Shin’s recent work before diving into his next project.
