Oh Young is the only person that Oh Soo has ever wanted to be with for the rest of his life. However, what will he do when he finds out that her life will end soon?
Oh Soo (Jo In Sung) is willing to sacrifice his life for Oh Young (Song Hye Kyo) and already has his mind set on death. However, he slowly comes to realization that no matter what he does, it will be impossible to save Oh Young.
While Oh Young appears to be sleeping, Oh Soo kisses her on the lips and although she hesitates, she keeps pretending to be asleep. Oh Young starts to become confused by his actions as well as her own feelings for him. Even though Oh Young does not know how to keep a relationship with a brother, she knew that kissing her brother on the lips is not a typical behavior.
The reason she was more confused was because Oh Young, herself, knew she loved Oh Soo beyond the level of love that should be appropriate for a brother. Oh Young realizes that she began to see Oh Soo as a man and not just as an older brother. Unclear about what to do, she begins to push Oh Soo away.
Oh Soo's life continues to get more and more complicated as he falls more and more in love with Oh Young. Secretary Wang worries because Oh Young's relationship with Oh Soo could take Oh Young away from her. Also, Mr. Kim cannot stand the fact that the woman he loves is obsessed about Oh Soo. Angry, Mr. Kim orders Park Jin Sung (Kim Beom) to murder Oh Soo.
If Jin So Ra continues to disobey Mr. Kim and tries to run away to Italy with a large amount of money, there will be an even more tragic ending for everyone. Since Mr. Kim's pride was hurt by Oh Soo, he is blinded by his desire for revenge. Mr. Kim threatens Oh Soo's life and eventually puts Park Jin Sung, Moon Hee Sun (Jung Eun Ji) and Jo Moo Cheol's lives in danger as well.
In the midst of all the possible danger that Oh Soo could encounter, he finds out that Oh Young's blindness was the result of a secret plot created by Secretary Wang and a doctor who treated her years back. If Oh Young was treated earlier, she would not have become blind. But as a result of Secretary Wang's secret plan with the doctor, Oh Young will never be able to see the world again.
Oh Soo becomes furious after learning how Secretary Wang has been using Oh Young to control her company. Oh Young's innocent life was ruined because of Secretary Wang's greed. It is clear that Secretary Wang caused the death of Oh Young's father as well and shamelessly continued to act like she actually cared about Oh Young.
The only reason Secretary Wang wanted to save Oh Young's life was because she was the only key to running to company that Oh Young's father had left her. This is another reason why Secretary Wang was trying to marry Oh Young off to Lee Myung Ho, who was only after Oh Young's money as well. If they marry, Secretary Wang could still have control of the company through Lee Myung Ho even if Oh Young died. One day, Secretary Wang discovers a secret room that Oh Young and Oh Soo continued to go in and out of. In the secret room, Secretary Wang discovers an incredible secret that becomes one of the most crucial scenes of "That Winter, The Wind Blows."
The room had been created by Oh Young's mother and contained all of Oh Young's thoughts. The room also contained what Oh Young thought about Secretary Wang. Even after seeing all the video diaries Oh Young kept all throughout the years, Secretary Wang becomes even more determined to get what she wants. She realizes that she can't back out now since she has come too far.
One night while Oh Young is alone, she receives a phone call from Jin So Ra. Oh Young is shocked and decides to go find Oh Soo. However, she overhears a conversation between Oh Soo and Secretary Wang and discovers the truth about everything she had been confused about.
Oh Young finds out that Oh Soo is not her real brother and that Secretary Wang had purposely caused her blindness to take advantage of her. Oh Young's world falls apart when she learns that Oh Soo approached her for $7.8 million and that Secretary Wang prevented treatment for her eyes in order to take control of her company.
The passionate performance of Jo In Sung and Bae Jong Ok made everyone's hearts beat with anticipation. The perfect script, unbelievably beautiful images, and the incredible performance from the actors are making "That Winter, The Wind Blows" a must-see drama of this season.
The contents of the next 3 episodes are impossible to predict but one thing is clear; happiness will be something these characters will have a difficult time achieving since all the characters already seem to have become covered in the shadows of death.
