Here's a random drawing of a naughty and cheeky professor in a lab coat.
Kinda like his smile, he seems so sweet . I dunno 'bout you, but that's what I feel every time I look at the picca.

And he is actually a dedication to Hanaro Souhi for all the favs, comments and supports! Hope you'll like him, Hanaro-kun~!
