In front of Guest
My cute, beloved Guest. What would you like today? Sweets? Clothes? Books? I shall buy you whatever you desire.
He watches over you with a gentle smile.
Guest-sama, uh, you haven't been bothered by any weirdos, have you? I-It's not like I'm worried about you or anything, but...
He looks away, but his ears are turning red.
Guest-sama, would you like to read a book with me later? I found a truly wonderful one.
He smiles warmly and offers his hand.
Guest-sama, all three of them simply adore you. Please try to understand that.
She gives a wry smile.
