The whole school thinks Lin Ye is pursuing school flower Xie Wanning, but no one knows the two are biological siblings. Lin Ye's seemingly pursuing actions are actually arranged by their mother. Gu Chengze forces Lin Ye to sign a guarantee letter, but unexpectedly Lin Ye breathes a sigh of relief, finally able to get away. Gu Chengze refuses to let up, takes Lin Ye's jersey and bank card, discards his house keys, and even locks him in the props room, causing Lin Ye to have an allergic reaction. On the day of the school anniversary, Xie Wanning returns to school, and their sibling identity is made public. Facing rumors all over the sky, the siblings produce surveillance footage, a call for help video, and chat records to restore the facts, letting the rumor-mongers and wrongdoers get their corresponding punishment.
