Dohee is too busy girl-bossing her way up the corporate ladder to care about love. Her ability to randomly time loop makes her professionally successful but also renders all relationships meaningless. What's the point when she'll have to restart everything at some point? That all changes when Joonwon, her annoying new boss, reveals that he can time loop too. Though she cringes at the mere sight of him, he's also the only person who understands her. Will they learn how to find solace in each other, or will their professional friction mess up their one chance at love?
