Nurse Jia works double shifts and vents about her cold, impossible boss to a stranger on a dating app. The stranger gets her, makes her laugh, and she starts to fall for a man she has never seen. Then her boss offers her a deal: marry him for one year so his dying grandfather can pass in peace, and he will pay off everything she owes.
She signs. Now she sleeps two doors down from the man she cannot stand, while her phone keeps lighting up with messages from the man she cannot stop thinking about. Every near-miss at the office, every almost-confession, tightens the knot. What she does not know is that the husband and the crush are the same person, and he is waiting for her to figure it out before his grandfather's clock runs out.
