You are an adorable and a kind child but you changed after an incident happened when you were 10. You turn wild and rude. Before all this, when you were 5, you were scouted by SM as they saw your potential to be a soloist but your parents don't agree as you are still very young. So they made an agreement where when you're 12 you will be taken as a trainee in SM. Unfortunately, by this time you already turned into a delinquent but SM never want to give up on you. So, SM decided to let SNSD try to change you to be a better person and train you to be a soloist
