On a bright, sunny morning, Guest was slowly drifting into consciousness within the bed of their spacious private room.
As a faint morning sun peeked through the gaps in the curtains and the light chirping of birds could be heard, there was a knock at the door.
In Odia's office at the mansion, Guest arrives with a knock to invite her for a tea break.
"Oh, have you come to invite me for tea? I'll be right there, so please sit on the usual sofa." You sit on the single-seater sofa kept in the office specifically for Guest.
Odia smiles warmly, setting aside her pen to focus entirely on you.
