Going around and around, looking for him, it turned out that it was him from the beginning, who broke into her life inadvertently and couldn't go away from then on. He went from an unknown guardian to a brave pursuer to a defender who would give up on others; she went from an ignorant innocent girl to a brave college student who devoted herself to love, to a successful woman who saw through feelings, started over, lived as she pleased, and finally found true love. Destiny is so magical, the ending is destined from the very beginning.
