Lin Xiaoman, an "overtime regular" at an advertising company, has been kept awake by cicada songs from downstairs for a week. When she goes to confront the culprit, the door opens to Gu Shiyan—the "biology geek" she secretly sketched in high school. Now an entomologist, he’s raising a "seven-day cicada" that lives only a week. To her shock, the cicada’s song matches the recording of her missing mother. As the seventh day nears, Gu’s seven-year secret is revealed: he gave up studying abroad to help Xiaoman find her mother, and the cicada is a "token" her mother entrusted to him on her deathbed—to tell Xiaoman "someone is waiting" on the seventh day. When the cicada sings, Gu holds up her old sketchbook and smiles: "I spent seven years hiding 'I love you too' in every chirp."
