For 18-year-old Xing Yushan, "Bi Ran" sums up everything she thinks about love. He taught her what love is and how to love. She gave him all the warmth she could give, making up for the lack of love from his parents. Just as she was gradually incorporating him into her future, he wanted to leave without looking back, "Xing Yushan, I don't love her, I love myself more than I did back then." A long time passed, and when her youth faded, he said to her again, "Xing Yushan, I have a plan to reset my youth, and I need your participation."
Purpose: love and hope
