Dao Ming Temple accidentally discovered a letter given to him by Lei during the farewell, and decided to give Cai a surprise. He bought the meteor ring that Cai liked and hurriedly drove to the church where he had an appointment with Cai. However, an oncoming sports car changed his life.
In the second episode, Cai waited in front of the church but never saw Temple arrive. Finally, she had to seek help from Teng Tang. Quietly waiting, Cai searched for Temple in the city of Barcelona. She learned from a stall owner that Temple had bought a ring, as well as a bad legend about the ring. The unconscious Dao Ming Temple finally woke up.
