Escape

Prologue. I married a man who has a high school daughter named Aiko. Even though we've been married for 2 months now, Aiko still won't even look at me. She's at a difficult age now, so I decided to wait until she would accept me. When doing the cleaning, I entered Aiko's room. But I got locked inside! Your mission is only to Escape from the room by opening the door.
