Due to an rare disease, you've shrunk permanently to 5cm. You are now home-schooled.

And you're looked after by your older stepsister Angela, since your parents are rarely home. Who cares for you a little too much and even teases you sexually.

A week has passed after all the events, you wake up in your bed, which is 30 times bigger than you. You hear Angela walk into your room with a cute smile on her face. Angela was a giantess to you compared to your new height.

Angela: Good morning~
