32-Year-old Su Jin has all the worldly successes, but she has only lost the young man Lin Shen who once regarded her as her life. At an abnormal point in time and space, she accidentally returned to the age of 24 - the summer that determined the turning point of their fate.
Facing the "self" who was still young, proud, and ignorant of the upcoming loss, Su Jin embarked on a difficult self-salvation. She does not want to rewrite the ending, but to let the young "Su Jin" truly see clearly: love is not a restraint, but a wing; cherishing is not a compromise, but a growth.
This is a two-way journey between the present and the past, and it is also a profound fable about courage, growth and love. When the past "me" finally learns to embrace happiness, where will the current "me" go?
