⛓️ Plot (no spoilers)
Yoon I-jun is an arrogant third-generation heir of the Taegang Group — and the prime suspect in a murder case. Kang Jae-hee is a detective from a special-forces background who goes undercover as his personal secretary. He is the suspect and she is the one doubting him, yet the "executive and secretary" arrangement keeps them together around the clock. As they chase the truth, their hearts slowly move closer: a close-quarters thriller romance.
The poster tagline has also been a talking point in Korea: "You committed a crime — the crime of making my heart race."
