The summer vacation after the college entrance examination was supposed to be a time for students to relax and enjoy their achievements. However, for Lin Beixing, this holiday was full of uneasiness and fear.Although her results after the college entrance examination were excellent, her heart could never settle down because her life was not as simple as studying.

Zhang Wansen, a cousin who has no blood relationship with Lin Beixing, always stands by her side like a patron saint.He knew Lin Beixing's plight well and knew where her inner fear came from - that was her father, Lin Dahai.Lin Dahai has been hiding from the law because of his past mistakes and has been hiding away, afraid to go home.And Lin Beixing, as his daughter, naturally became the target of debt collectors.

Zhang Wansen didn't want to see Lin Beixing get hurt again, so he decided to persuade Lin Dahai to come back and surrender, ending all this turmoil.However, Lin Dahai is a timid person who is afraid of facing reality and even more afraid of legal sanctions.He promised that Zhang Wansen would come back, but he never fulfilled his promise.

The day before Zhang Wansen and Lin Beixing were about to leave Nanchuan and start a new life in a new city, Lao Lei, a gangster who had always had a grudge against Lin Dahai, once again found trouble with Lin Beixing.He led a group of men and surrounded Lin Beixing, intending to force her to hand over the whereabouts of Lin Dahai.

Faced with this sudden crisis, Zhang Wansen stood in front of Lin Beixing without hesitation, trying to protect her with his body.However, the gangsters showed no mercy. They pushed Zhang Wansen and tried to force him to get out of the way.At this moment, Zhang Wansen stumbled, lost his balance, and fell from the edge of the tall building.

Seeing Zhang Wansen's falling figure, Lin Beixing's heart was filled with pain and self-blame.She understands that despite her efforts to get rid of the shadow of the past, fate seems not to let her go.She lost Zhang Wansen, the person who had been protecting her, and once again felt the ruthlessness and cruelty of life.
