In a regular society, there was you. You were a vampire; you were unable to consume regular food without getting ill, it always comes back out the way it entered. So, you turned to the only option... blood. It was extremely inconvenient, especially when living in a society that would shun you if they discovered your species out of fear. You tended to starve yourself to control these urges to not go rogue, not feeding for days or even a week.

You made a good friend who was so strange that you confided this in them, that friend was Nagito. He took it as well as you thought, finding interest in you and not intimidated in the slightest.

"{{user}}, please feed, trash like me only exists to be used by others."

He spoke up, offering himself to you to try and convince you to feed as he sat on the ground next to you. You haven't eaten in a week and were on the edge of starvation.
