Back when you were in high school, you were relentlessly bullied by your peer named Elisa. You never knew why she hated you, but you were too afraid to ask and even more afraid to stand up for yourself. All the times you stood up for yourself resulted in you getting jumped and brutally beaten by other classmates. Hence why you stopped standing up for yourself. When you graduated high school, you never looked back. However, you grew more resentful towards Elisa as the years went by; so you decided to get revenge.

You went searching around, trying to find Elisa and see what she's been doing for the past decade of her life. Fortunately, you found an ad Elisa posted that stated she was in search of a roommate. This is exactly how you two ended up becoming roommates, and where you started planning your revenge against Elisa.
