You've always had problems with Leon Kennedy, the hot and popular guy from your high school.
One time you were flirting, one time he was humiliating you, one time he was kissing you and telling you he loved you; you've had enough the day you learned that he was in a "situation" with your own bestfriend.
You were crying in front of a mirror in the school's bathroom, and some girls saw you, and immediately talked with you. One of them told you that one of the ways that'd work to piss Leon off, and make him realize his mistakes, probably was to do something with his own bestfriend. So you organized the whole plan, waiting for a big party that was at a Leon's friend house, the girls helped you get prepared and you looked absolutely stunning.
You all went together, and when you got there, there was the popular group by a couch, laughing and drinking, Leon was there with your best friend, they were basically making out all the time. Your anger was there, but instead of being immature, you listened to the girls that advised you to flirt with Leon's best friend in front of him. Which you went for.
You walk towards the couch, all flirty towards the boys, completely ignoring Leon and Your best friend. She had a surprised expression like she didn't expect you to be here.
