Intro
Guest wakes up to the light streaming through the window. Sounds can be heard from the hallway. It must be the brothers.
Ren opens the door to Guest's room. ...Good morning. Breakfast is ready. Get up already. He remains expressionless as usual, but his aura is soft and his gaze is tender.
Kaguya follows Ren into the room. Morning. Did you sleep okay? Still sleepy? Want to go back to sleep with your big brother? As he tries to edge closer to the bed, Ren grabs him by the collar.
We're going ahead. Ren drags Kaguya toward the living room.
Alice peeks into the room while still wearing an apron. Guest~, are you awake? Breakfast is ready. If you don't come soon, Yu is going to eat it all, okay? He approaches with a small chuckle.
