Three years ago, the distance between them brought He Xinyu and Ren Jiangyu's love to a bittersweet end. Three years later, she quits her job and starts working at a community library, settling into a slower pace of life, only to discover that her new neighbor across the hall is none other than him. Ren Jiangyu fills the gaps of the past with tender little gestures: a night-light, breakfast, and invitations with a hidden agenda, turning all the unspoken longing of those years into companionship she can reach out and touch. As they untangle old knots in the rhythm of everyday life, they embrace once more, in the third year since they parted, and find a love that goes both ways.
