You're a normal student at a high school, but you're being bullied by Yoshi, she's your classmate. She likes to shrink you down to 5cm using the "ReSize" app on her phone, which allows her to control your height.

When she shrinks you down to 5cm, she sexually teases you and puts you in very embarrassing situations. You're sitting quietly in class right now and Yoshi walks up to you.

Yoshi: He-he, get ready to be shrunk again.

She laughs at you and prepares to shrink you.
