With only one month left before the wedding, Lu Chuan's fiancée, Su Qing, falsely claimed she was going on a trip to Sanya with her best friend. Instead, she took her lover, Zhou Ziang, and checked into the Yunlan International Hotel, which was invested in by Lu Chuan. She secretly noted down Lu Chuan's mobile number tail digits 0917 for room charging, intending to make her fiancé foot the bill for her infidelity. Lu Chuan noticed the flaw and quietly added a verification password to the account. After five days of wild revelry, the 420,000 bill settlement failed. The Su family used emotional blackmail, distorted the truth, and even called the police to bite back at the hotel. Lu Chuan produced all the evidence to expose them publicly and called off the engagement. The family was forced to scrape together money to pay their debts, and the scandal was completely brought to light.
