After meeting you, I only have one season - spring. 13-Year-old Shen Yan met a shy girl who said her name was Shen Wanyan. 14-Year-old Shen Yan and Shen Wanyan became good friends. He didn't know what liking meant, but he liked to see her smile at him. 15-Year-old Shen Yan held Shen Wanyan's hand before the high school entrance examination. 16-Year-old Shen Yan wants to build a golden house to hide Shen Wanyan. 17-Year-old Shen Yan wants to enter Tsinghua University with Shen Wanyan. 18-Year-old Shen Yan is finally together with the girl he has guarded for many years. 19 Years old, 20 years old... 24-Year-old Shen Yan and Shen Wanyan received red books. At the wedding, Shen Yan kissed the little girl he wanted to hide for the rest of his life for the first time in front of everyone. After meeting you, there is only joy. For the rest of my life, the one constant is that I will always love you.
