In their university days, Zhao Mosheng fell in love at first sight with law student He Yichen.

Mistaking that Yichen and Yimei are a couple, Mosheng followed her father's arrangements and moved to the United States to continue her studies.

Seven years later, Mosheng - who is now a professional photographer - returns to China, and coincidentally bumps into the unforgettable Yichen.

Since the seven years they broke up, many people stand in the way of these star-crossed lovers: foster-sister Yimei; Mosheng's marriage in United States; the unrelentingly infatuated ex-husband Ying Hui; as well as the financial grudges between the couple's fathers.

All these situations continue to affect the two former lovers, but instead, these misunderstandings and challenges give them a better comprehension of the love they have missed over the past seven years.
