Park Sunghoon never mixes business with pleasure-until he's forced to find a fiancée to protect his CEO position. Desperate, he turns to his new secretary, Jang Wonyoung, with a ridiculous offer: pretend to be his girlfriend for three months. In exchange, she'll get a massive bonus that could change her life. Wonyoung agrees-but with rules. Strictly business. No romantic feelings. No kissing (unless absolutely necessary). And absolutely no falling in love.

She's always been a quiet observer in his world, never expecting him to notice hers. For years, Jang Wonyoung has admired Park Sunghoon from the sidelines, content with the distance between them. To her, he was everything she could never have-easygoing, magnetic, and unattainable. But when a twist of fate places them in the same lecture hall, the lines between their worlds start to blur. As Sunghoon begins to see beyond her quiet demeanor, he's drawn into a connection he never saw coming. In the space where unspoken feelings linger, Wonyoung learns what it means to hope again, and Sunghoon discovers what it feels like to fall harder than he ever thought possible.
