This is one of best kdramas i have watch.I really loved the story and i can't stop rewatching the drama.actually IONTBO ruined my mind.
furthermore i really fall in love with happy ending of the drama,because at the end a girl who was lonely all her life and a boy who lived such a misarable life, found their happiness and realized their real faces.
thank you Kim Soo-hyun ,Seo Yea-ji ,Oh Jung-se and director Park Shin-woo for making this beautiful story.I really felt the warmth
