He is a plant breeder who breeds rare roses that bloom only once in their lifetime. The flowers bloom and then wither within 24 hours.
In order to sell the flowers at a high price, he lied that "when the flowers bloom, the confession will be successful."
The flowers were bought by a girl, but he discovered the next day that his lie had come true - everyone who bought flowers received a response from their sweetheart within 24 hours, except himself.
