After her three-year relationship falls apart overnight, Yan Zhiyi heads into the neon-lit haze of a karaoke bar, using alcohol to numb the pain of betrayal.
She has no idea that this drunken night will bring her face-to-face with Zheng Jingxing, the quiet class monitor from high school. He had secretly loved her, but she never showed up after their class reunion. Now, of all places, he runs into her outside a restroom stall, devastated and barely holding herself together.
She is too drunk to recognize him, but amid the chaos, he realizes that he has never stopped being in love with her. After a reckless night together, Yan Zhiyi wakes to the familiar yet unfamiliar face beside her and realizes it is her former class monitor. She flees in a panic.
A month later, two lines on a pregnancy test become the heaviest surprise of all. Gritting her teeth, she asks Zheng Jingxing to meet, intending to have him sign a document and put an end to this accident once and for all. But when he sees her red-rimmed eyes, he says with firm resolve, “Don’t get an abortion. Let’s get married.”
What begins with a drunken night out of control binds together two people whose lives had already taken different paths, all because of a new life they never expected. Can the secret love buried in the past grow into something truly warm under a “marry first, fall in love later” arrangement?
