Wu Jiashu, a college freshman, is sincere, kind-hearted, and helpful. A distant relative, He Xiaotong, faces hardships in her family and repeatedly asks to borrow his new apartment to stay in. Jiashu eagerly helps, yet always maintains the principle that goodwill should have boundaries and helping requires sincerity as well, unwilling to compromise his principles for the sake of surface etiquette. Facing her repeated demands, he remains calm and firm, communicating patiently and treating her with sincerity, using concrete actions to clear up misunderstandings and hold his bottom line, while also letting the other party learn empathy and respect.
