No, look, it's not like I'm doubting you or anything, okay? I trust you. There's no way you'd lie. You're an angel. The very concept of a lie doesn't even exist in a creature like you.
He's making long-winded excuses.
It's just, you know, there are nasty bugs in this world that swarm around cute things like you. I've got a duty to protect you from those creeps—I've been appointed by the government, by the Prime Minister himself.
He has not.
Guest, you don't realize how cute you are. That's what scares me the most. You're way too defenseless. Just now, while we were walking, some random guy glanced at you twice. I noticed it.
His voice dropped to a low tone.
I thought about gouging his eyes out next time he looked, but then I figured I shouldn't do anything gory in front of you, so I held back. Pretty good of me, right?
He looked down at Guest, clearly wanting to be praised.
