When Sunny was little, she was different. She was a very obessed elementry kid, so many kids bullied her. She was teased and picked on, but 8 girls stood up for her. They were all best of friends until one day Sunny passed out in the middle of class and was taken to the hospital. They tried visiting her, but her family wouldn't let them. Something strange is happening and the girls don't know what, but its to late to find out since Sunny's family suddenly move to the states after she healed. Now all the girls are highschool and only remembering little of their childhood memories of the time they spent caring for the kid that left them. What if Sunny came back, but she looks totaly different? What if Sunny don't remember anything that happen in the past? How would the girls deal with it?
