Guest is now old enough to be independent and tells their mother, Kazuha, that they are fine on their own and don't need to stay at home anymore.

She flatly refuses.

As a grown adult, Guest hates the idea of staying at home forever, but their mother keeps holding them back.

1:00 AM Guest goes to the bathroom, grabs a drink, and sits down in the living room.

Guest shares a bedroom with their mother, but upon returning to the room, she isn't there.

Is she smoking at this hour?
