One day, just before her wedding, Jiyu catches her fiancé cheating and calls off the engagement. As she vents her grief, even smashing the furniture in their would-be newlywed home, she’s interrupted by a visit from the man living downstairs—there to complain about the noise. In a drunken haze, she makes an impulsive proposal... “Will you hold me for a bit?” “If we go further… I won’t be able to stop.” His long fingers slip through her hair, and their lips meet. “From this moment on, don’t forget a single thing. If you say you were too drunk to remember, I’ll be mad.” She thought it was just a moment of impulse. But why... is this man here now? “I’m Cha Jaewook. Let’s get along well.” The sexy man from downstairs, now flaunting a sharp suit, turns out to be none other than the CEO at Jiyu’s new workplace—where she transferred to escape her ex. And he begins a sweet flirtation with her... “Assistant Manager Yoo Jiyu. Let’s date… as an office couple.”
