As a girl, Su Wan accidentally spilled hot soup on her senior student Lu Shiyan's shirt. The clumsy patch she sewed onto it became the beginning of their bond.

As they grew close again among the city's lanes and streets, the old garment stirred more than memories: it brought back the heartbeats they'd missed and the confession they never finished.
