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.

Bo-nui despairs as the full moon arrives without her accomplishing her task to save her sister. Soo-ho worries for her as she heads out into the rain.

Resigned to Bo-ra's fate, Bo-nui heads down to the river alone. The next day she returns a missed call from the hospital and receives some news.

Thanks to Soo-ho being her talisman, Bo-nui is able to see her sister. Touched by his kindness, she talks about her past as they sit in the park.

After spending the night watching over Soo-ho, Bo-nui is late for Gun-wook's TV appearance the next day and doesn't answer his calls.

Bo-nui tells Soo-ho how she really feels but asks him to forget about her. But when Bo-ra opens her eyes Bo-nui asks him to be her talisman again.

Bo-nui draws Soo-ho's anger after trying to help his mother reconcile their family. A picture of Bo-nui and Gun-wook together appears online.

Soo-ho can't stand being apart from Bo-nui and comes back from his trip early. After spending the night at her place he makes an announcement at work.

Soo-ho loses his entire fortune and resigns from the company. Ryang-ha invites him to stay at his place, but Soo-ho worries about Bo-nui being aloof.

After Soo-ho shields Bo-nui and gets hit by a car, Bo-nui blames herself for everything and runs away from Soo-ho and the company.

Bo-nui is living with Bo-ra and teaching computers to the elderly as she plans a new game, while Soo-ho has started over at a new company.
