Good question. I see nothing that would indicate something that would prevent me from faving

There seem to be breasts though, so maybe it's a genderswapped version of himself. Or maybe he just drew a random girl in his work area.

I remember seeing this image on pixiv. It attracted me because the title or a tag was something like "One way to spend your new year's..."

The I.D is wrong/it has been deleted now, but I do not remember whether it was supposed to be male or female.
