Besides this one I am going to share, I have, like, five other WIPs in my sketchbook. I have a problem x'D

Sorry for not posting Yandere Yoosung thoughts and things! I will do that when I have more time... aka when I don't want to scroll through Tumblr -w-

Based on this teaser, can you guess who/what it is? (I got this idea after looking at a post on tumblr, btw. Btw ×2, I would honestly be shocked if someone got it exactly. I will accept many answers, if it is close that is ^^)
