In this K drama/ Korean show, Shim Bo-nui searches at a casino for her boss who ran off with her salary. Meanwhile, Je Soo Ho is about to announce his company's new game, Genius II. Two of the engineers try to steal the software on the day of Soo Ho's presentation.

After Bo-nui's attempt to catch a tiger ends in failure, pro tennis player Choi Gun-wook moves into her apartment building.

Bo-nui lets Soo-ho into her room after mistaking him for her date, but now Gun-wook waits outside. Bo-nui frantically stops Soo-ho from leaving.

Bo-nui agrees to the contract on the condition that Soo-ho dates her for three weeks. She tells him that it's a matter of life and death.

After seeing Soo-ho's gentle side Bo-nui asks him to spend the night, only to be refused. Gun-wook takes the downcast Bo-nui to the tennis court.

Bo-nui tries to apologize to Soo-ho and tells him the truth but he drives away. Soo-ho can't keep his mind off her and follows her after work.
