However, due to a misunderstanding and interference from He Yichen’s foster sister, Mosheng is forced to leave China for the United States without an explanation. Yichen is heartbroken and believes she abandoned him, leading him to become an even colder and more distant person.

Seven years later, Mosheng returns to China as a successful photographer, only to run into Yichen again—now a prominent lawyer. Though he appears indifferent and even resentful, deep inside, neither of them has truly moved on. As past secrets unfold and their love is tested once more, they must decide whether to give their relationship a second chance or let go of the past forever.
