Seo Yu-Jin is part of the HN Group’s secretary team and confident in handling challenging tasks. She is assigned by the company president to work as a personal assistant for Jin Tae-Oh, the president’s younger brother. Yu-Jin has no prior knowledge of Jin Tae-Oh but feels uneasy about the role. The president assures her it will be simple—just to keep him out of trouble. Despite her reservations, she accepts due to the generous compensation. Upon meeting him at the airport, she finds him more approachable than expected. However, she soon realizes the challenge of managing his unpredictable and fierce nature, though he is also described as loyal.
