Coming back skinny and beautiful, she tries to move on from her past but later on finds out she can't because she bumped into someone unexpected. Her first love, Woo Ji-ho. . . . . "I can't give you much but... If I could give you one thing in life, I'd give you the ability to see yourself in my eyes. Then, and only then would you finally realize how special you really are to me."
