Cheng Ye fully funded and arranged the graduation trip for the whole class, but because he refused to pay for three off-campus people brought temporarily by the class beauty, he was mocked by the whole class and kicked out of the group chat. Faced with isolation, Cheng Ye promptly cancelled the hotel, vehicle, and official guide orders under his name, and sought peace elsewhere with his friend. The classmates, who had lost the free arrangements, arrived at the destination and ignored warning signs to save money, forcibly breaking into an unopened and dangerous mountain forest. In the end, they got lost deep in the mountains and suffered serious accidents, and those involved had to face severe accountability afterward. Cheng Ye, who had stuck to his principles and withdrew from the trip early, came through completely unharmed.
