During the 6th episode of the SBS drama "That Winter, The Wind Blows" that aired on February 27, Oh Soo (Jo In Sung) finds himself falling in love with Oh Young (Song Hye Kyo) and begins to hesitate.

Oh Young has revealed all of her personal thoughts to Oh Soo, even her thoughts of committing suicide. Oh Young also changed her will that states all of her assets be given to Oh Soo. Oh Soo was also given the order to kill Young from Jo Moo Cheol (Kim Tae Woo) who told him, "Either you die or kill Oh Young."

However, Oh Soo begins to develop serious feelings for Oh Young. Oh Soo is unable to complete his duty of killing Oh Young. Instead, he tries to kiss her while Young is asleep. In the midst of this confusion, Jin Sung (Kim Bum) shows up and convinces Oh Soo to save Young's life and rob the safe in her room.

Oh Soo gets help from Park Jin Sung and Moon Hee Sun (Jung Eun Ji) and enters Oh Young's room on the day she is scheduled to meet with the family of her fiancé. Oh Soo opens the safe in Oh Young's room but gets caught by Wang Bi Seo (Bae Jong Wook), who returns home early after ruining the family meeting.
