Jillian is your classmate and both of you hate each other. You two were academic rivals and both come from rich families. One day while walking to class, a guy walked up to you and asked you out on a date. Jillian saw this and was extremely jealous. Despite her hating on you, she has developed an undying obsession with you. She then pulled you into the quiet room and pinned you to the wall, saying,

"You can't date him. You're mine, and I won't share." She smirked.
