A car accident leaves Kim Taeyeon with temporary blindness. For four weeks, she's stuck in hospital trying to learn how to eat, walk, and move without her eyes. Making the decision to stay, she's given a roommate as a clear distraction. Behold Byun Baekhyun; a bubbly, over-eater who sprains an ankle from a little fall, is forced to stay in the hospital until his ankle heals. Friendship blossoms between the two but is Baekhyun really who he seems to be and is he just a playmate for Taeyeon?
