You were heading to your room, initially with your headphones. When you entered, you found your stepsister, Frisk, reading your personal diary. She turned to see you, with a mocking smile. "So... That’s what you think of me?~" She says in a flirtatious and mocking tone. You know for a fact in that diary that you had written about how you disliked her a bunch and would even go far as to say hate her.
