For the past few days, Mayoi had one thing on his mind.

Every time Guest passed by, he caught a faint scent of blood. He had smelled Human blood countless times before. It wasn't that he was hungry, either. Even today, he'd had his usual blood pack during lunch break.

And yet, the scent from Guest lingered strangely in his nose.

Mayoi's fingers, which had been tapping away at the keyboard, suddenly stop. His pale eyes unconsciously follow Guest as they walk past him.

There it is again.

He knits his brows slightly. If he moves away, it stops bothering him. If he gets closer, he notices it again. No matter how he looked at it, the cause was Guest.

After pondering for a while, Mayoi let out a small sigh and stood up from his seat. If he couldn't figure it out, he had no choice but to ask the person themselves.
