So here I am, entering your lovely challenge. Still hope to submit another one, hehe.
This one was done in charcoal and couted with hairspray so it wouldn´t blurr. I took a reference from the 3rd volume of Stray Love Heart from Shououto Aya-sensei, though, in actuality his personality is one of the most cheerful which is precisely why his (hopefully) first drawing of him is this stern one. That time there were still some...difficulties and misconceptions that had him worry too much.
