Gong yoo has elevated his moviestar status with this film. Although I only watched it now, it truly touch a chord to my inner emotions and marriage in general. Everyone deserves to be happy, and although fate might bring to have a forbidden love .... correct the wrong and start all over ..its being in love and happy that matters in the end. I would have preferred a happy ending as this is a love story after all, but the ending was just right. He made the choice and in the end, someone has to cry harder . Maybe in a different life they will see each other again.
