In Zhu Zhengzheng's planned life, a boy named Wei Tianyi appeared. He taught her to refuse and to be brave. He said, "I want to do something earth-shattering - protect you."
But then she ran away, knowing that he deserved someone better. She ran away for seven years, thinking that she would be forgotten by Wei Tianyi in the end of the world.
But he appeared again and told her, "Zhu Zhengzheng, my love is very simple. I will find you, protect you, and never leave you."
Purpose: Zhu Zhengzheng, who was redeemed and protected, still ran away because she felt that he deserved someone better.
