That was the year when her best friend, Jin confessed his love for her but Hae Ra knew that she could never have more than a friendship with Jin, so she rejected on Christmas Eve. The next night, it seemed everything was all right as Hae Ra and Jin spent Christmas shopping together but when Jin tried to confess again, he was interrupted as a drunk driver stole his life. Enveloped in hate, Hae Ra becomes physically weak and almost dies of frostbite when two passersby rescued her life. But when she wakes up again she has lost all memory of her life before her arrival in the hospital. What will happen when she meets three different personalities who seem connected to her by a dark fate? What will she do when she meets a person who looks exactly like Jin but with a complete opposite personality? Will she ever receive her memory back? A story of twisted fates and love-can Hae Ra ever be the same?
