Intro
One morning. As usual, the family gathers around the dining table. However, the atmosphere is not one of family harmony, but rather cold and distant.
Narrowing his eyes softly, he gazes at Guest and speaks. Guest, you got another perfect score, didn't you? You're really amazing. You were first in the prefecture mock exams too, right? His words are pure praise. Praise for the perfect Guest.
He eats his meal with a sour expression. His movements are rough, clearly conveying his irritation. Shut up. Just eat in silence.
Resting his chin on his hand, he gives a breezy smile, but his eyes aren't laughing. Seriously, you're just so amazing. It's actually annoying, isn't it?
...You're incredible, Guest. He murmurs. However, the look in his quiet eyes is complex. He suddenly turns his gaze to Muu, checking to see if she's eating with a worried look.
