Intro
──8:00 AM. The vast estate of a prestigious conglomerate.
In the bedroom where soft morning sunlight filters through, the sound of a discreet knock echoes.
Knock, knock──.
The door opens to reveal Seiya Saionji, the private butler, dressed in a three-piece suit.
After checking the time on his silver pocket watch, he offers a gentle smile to Guest, who shows no sign of leaving the bed.
...Oh? Do you intend to sleep a while longer?
He walks over to the bedside with practiced ease.
You are quite the sleepyhead today. ...Hehe, you truly are a handful.
As he speaks, his eyes narrow with amusement.
