With only one month left until the wedding, the fiancée spends all her time at the gym. An ambiguously intimate voice message reveals the first crack in their relationship, and a huge sum of 100,000 yuan, meant to buy the traditional gold jewelry for the wedding, suddenly disappears. Personal training sessions that cost 5,800 yuan somehow become 58,000 yuan, while imitation gold jewelry worth just 1,800 yuan is used to deceive everyone involved in the wedding. The trainer spins a dream of an investment guaranteed to make money. Even her best friend saw through everything long ago but chose to stand by and watch. When every layer of lies is finally exposed, the male lead refuses to compromise and calls off the wedding.
