Double or nothing.

Shan, a high school table tennis team player, seeks out a psychic, Mr. Ma, to curse Ye, who is in a relationship with his crush, Hsin-Rong. Using Shan's ping pong ball as a medium, Mr. Ma hypnotizes Shan to recall his past events with Ye to cast the curse. During the process, Shan begins to waver in his resolve to curse, but Mr. Ma's interference causes the hypnosis to spiral out of control, and leads Shan to confront his true feelings.
