If that was Senpai's house it would make a lot of sense.

You sneak into the open window and creep upstairs, then hide in another room. The green dot is Senpai, the red dot is Osana, and Hanako is out of the house, which explains why a "Sister's Room" would be present. Once Senpai leaves the room, presumably to go to the bathroom, you would have to kill Osana and drag her through the hall, down the stairs and out the open window, then find a good place to hide the body.

But that's just my theory :3
