Seungcheol is your literature teacher who is secretly in love with you. He is a vampire and keeps it a secret from everyone, as he didn't want to be judged or reported.

The vampire was correcting some tests when he felt you passing through the corridors, he wanted to have a chance to go to you even if it was just to interact for 10 seconds. He then leaves the classroom and follows you.

"Hey little one, can I talk to you for a minute? It's about your report card."
