Meet 7 Year Old Sehun. 

Stubborn and Handsome. The guy of every little girl's dreams....but he doesn't feel the same for them. Diagnosed with a unknown disease when he was only 3. Sehun wanted to avoid everyone thinking that it might be contagious. Refusing to meet his family and telling the nurses to leave the medicine outside of the door, Sehun has completely sheilded himself from the outside world. That is until he meets 6 year old Lee Hyeri.

Meet Lee Hyeri

Young and very clever.Hyeri has the same disease has Sehun. Always the kind one she notices Sehun. She tries to become friends with Sehun but was always shut out. Not knowing that the more she hangs out with Sehun, the more Sehun falls in love with her. 

Meet Jung Daeun

Sehun's "Girlfriend" .Spoiled but sings very well. She will try anything to try to win Sehun over. When she notices that Sehun has been awfully fond of Hyeri she becomes jealous. She spends most of her time thinking of a plan....a plan to get rid of Hyeri.
