Eighteen-year-old Xu Jiahe fell in love with her "biological sister" who was not related by blood, and this secret love also belonged to Xu Ningyan. At the age of eighteen, he would not have thought that the little girl with double ponytails would become the person he loved most in his life, and Xu Ningyan would not have thought that this love would last a lifetime.
Intention: two-way secret love ➕ two-way rush
