The two girls met when they were children, and their meeting again ten years later was not accidental. Jiang Shu recognized at a glance the girl who was chasing after him and called him little brother. But the girl didn't seem to recognize her. When the girl came to see her at home after school, she was naturally filled with joy. When Jiang Shu just wanted to protect her like he did when he was a child, he found that he liked her. Zha Nan also liked Jiang Shu since he was a child. When they learned that the other person was the same gender as themselves, they still loved each other.
When they took that step toward each other, Jiang Shu's biological father asked Jiang Shu to return to him. He used threats to force Jiang Shu back. Jiang Shu could only compromise. But when Jiang Shu returned to his biological father and brother, he returned to his previous state of depression because of the estrangement in his heart. At this time, Zha Nan was also in trouble. Jiang Shu begged her father to let her go back again. This time they saw each other again, and this time they were both a reunion and a farewell.
Many years later, after Jiang Shu's father let go of the incident, the two reunited again. This time, no one could separate them again.
