That winter, an accident caused 25-year-old Li Zhihe to meet 17-year-old Zhu Ye.
He has clean facial features and a clear temperament, but he will fight with people in alleys to protect others. When he had no one to support him because his parents were far away, it was Li Zhihe who stood up for him for the first time as his sister.
The warmth of each other's company makes the ambiguity grow quietly. On New Year's Eve, she looked into his eyes and spoke first: "Zhu Ye, when your college entrance examination is over, we will be together."
His eyes were burning and he answered without any hesitation: "Okay."
However, this beautiful agreement finally came to an end when he left without saying goodbye. For six years, Li Zhihe lived alone and tried hard to keep that name in his heart.
At the age of thirty-one, she decided to sell the old house that held the past and start a new life. But fate took a turn at this moment - the new homeowner and the new director of the airborne company were actually the same person: Zhu Ye, who had disappeared for many years.
The once innocent boy had become mature and steady. He crossed time and distance and stood in front of her again with an unavoidable persistence.
She has a knot in her heart and cannot forgive easily. But he took a deep breath and asked what he had been thinking about for a long time:
"Li Zhihe, does the agreement we made back then still count now?"
