Eleven years later, Shen Nian returned to her old place to look for him, but mistakenly recognized her benefactor because the token fell into the hands of the Sun family. After noticing doubts, she traced back past events and discovered that the person who helped her back then was none other than Zhou Yuan, who sold fish, yet he was always unwilling to acknowledge it. As the truth gradually became clear, Shen Nian understood his unspeakable suffering. The two finally resolved their misunderstandings, expressed their true feelings honestly, and continued the promise of back then.
