Vengeance

Lara Serrano is a girl who could alter fate. She's the ideal girl every guy wants to have and every girl wants to befriend. She's the 'it' girl, and the class' muse ever since. She's too perfect since she haven't had any mistakes at all. Intelligence, beauty, kindness. Name it, she has it. But what's the secret behind Lara's perfection? Oh, you would not believe her reason:

"She's a time traveller."

But that reason alone is a curse for her. She badly wants to commit a mistake. But everytime she does, time returns and make her do it again... repeatedly, without fail. She won't ever continue her life if she still can't make herself perfect at all times. It's an automatic switch, she does not need to press anything. She just... returns.
