Yim Si Wan Is a Ruthless Perfectionist at Work and a Soft Cat Dad at Home in Love in Disguise

Every workplace has that boss — the one whose gaze alone can end a meeting early. New stills from tvN’s upcoming drama “Love in Disguise” suggest Yim Si Wan’s character is exactly that person, right up until he walks through his front door and turns into someone else entirely.

The romance thriller follows an arrogant chaebol heir who becomes a murder suspect, and a former special forces officer who goes undercover as his personal secretary to investigate him. It’s based on the popular webtoon and web novel “Why Don’t You Know She’s a Woman?”

Meet Yoon Yi Jun

Yim Si Wan plays Yoon Yi Jun, the leading candidate to inherit Taegang Group — a man with sharp business instincts and no shortage of looks or ability. Raised to prove himself as an heir candidate from a young age, he’s internalized perfectionism as the baseline, leaving zero room for error at work and keeping his employees perpetually on edge.

The Contrast the New Stills Reveal

At the office, the newly released images show Yoon Yi Jun radiating cold precision — stern expression, sharp gaze, an executive presence that tolerates no mistakes. But at home, he’s a different man entirely: relaxing in comfortable clothes, gently petting his cat Jerry, and letting his guard down completely. It’s a classic “cold CEO, soft interior” trope, but the specific cat-dad detail gives it a distinctly warm, humanizing touch.
