Cafeteria owner Wang Cheng, out of sympathy for poor students, paid out of his own pocket to introduce a 5-yuan charity meal, only to be maliciously exposed and publicly mocked by student Zhou Qian. Feeling disheartened, he permanently canceled the meal and transferred to F University, starting over amidst respect and support. Faced with his alma mater's generous efforts to win him back, he still refused to look back, ultimately developing a simple act of kindness into a charitable cause covering multiple universities, making those who once hurt him understand that kindness can be passed on, but once a person's heart grows cold, it is hard to warm up again.
