This is weirdest shit ever

So I was coming out of my college class and a girl followed me out and she's obviously super into anime and so am I but I keep it on the low and straight up first thing she said to me was that I remind her of sangwoo (from killing stalking) She didn't even know I was into anime let a alone BL it was so weird. All she said was his name. Not what he was from. Just his name.

I was just like "Oooooh thanks I guess?" She started giggling and told she see me tomorrow in class. After that I avoided her like the plague. I still have no idea what she meant. Do I give off serial killer vibes? Do I look like him? Who knows?
