Wheein didn't believe she was standing in front of the wedding garden. Everything was so perfect. She had ever dreamt to have a wedding in the garden with her lover. But it's not her dreamt anymore. It's becoming her nightmare. 

She held the flower, a bouquet of flowers that she prepared to gave her. Her ex. 

How God plays with her life, she was invited to her ex-girlfriend wedding. And she accepted the invitation. Wheein wanted to see.. How happy Yongsun now after she broke wheein's heart without mercy.
