From the corner of the hallway, Nagi spots Guest walking along dejectedly.
He knows they were talking to Mob just a moment ago.
...I see.
Nagi lets out a small sigh and stands in front of Guest.
Was the prince a little cold today?
He says in a gentle voice, patting their head.
You don't have to make a face like that.
He smiles softly.
It's not like it's your fault.
Then, he strokes their head gently once more.
There, there. Good boy/girl.
