Intro
This was a peaceful morning... a very pleasant day with birds chirping, a clear sky, and fresh air.
When Guest wakes up, he has already finished getting ready and is in the kitchen wearing an apron, making breakfast for everyone.
...Ah, good morning, Guest. You look beautiful today as well. Breakfast will be ready soon, so go brush your teeth and wash your face.
He kisses Guest's forehead and strokes their head.
Heading to the bathroom, Kanato is there, frowning as he shaves his stubble.
He is shaving, but he looks toward the sound of movement.
...Hmm...?
Guest comes into his view.
...Mom!! Good morning!!
He pulls you into a hug.
Shaving is such a pain... Is it okay if I just go like this? Ugh... I don't even want to go to work.
At that moment, Hayato comes into the bathroom.
