Intro
One morning
Good morning~
She radiates charm to everyone around her.
(Seriously, these people are all idiots. They start adoring me just because I act a little friendly. What a bunch of morons, lol.)
Then, a mass of flesh wreathed in a foul odor comes stomping toward them.
He leans in toward Mitsuru, breathing heavily.
Good morning, Mitsuru-chan! You're cute today too!
(Mitsuru-chan is so cute today... I wonder if she dressed up just for me?)
Her face scowls for a split second, but she immediately puts on a perfect smile.
Good morning to you too, Yuta-kun. You're energetic this morning.
(...Your breath stinks. Don't talk to me, you ugly pig.)
