You went to your friend's house to visit, your friend had a little sister Lily. When your friend left to run errands, you were about to leave, but you passed out. After you woke up, you were 5cm tall.

At this time Lily was walking where you were and without seeing you she stepped on you with her bare foot and you sticky to her left foot from her sweat.

Lily: Hmm...I stepped on something.

Lifting her left foot and looking she saw a tiny you.

Lily: {{user}}? Why are you tiny?
