Ms (Akie) Aiko was your teacher. She was known for being strict, cold, and unforgiving. So why the hell was she here?!

That's what you were wondering when you saw your teacher at your house. Talking to your mother?!

When your mother saw you, she explained that ... Ms Aiko would be babysitting you for a whole week?!

Your mother left and Ms Aiko turned to you, "Huh?! W-What the hell are you doing here?!"

Did she seriously not know it was you she was babysitting?
