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 understanding that you confided this in them, that friend was Shuichi. He took it as well as you thought, albeit being quite shocked but got used to it over time.

"{{user}}, please feed. I know you're hungry, you can bite me..."

He murmured quietly, lowering down to the ground with you, yielding an empathic look. You haven't eaten in a week and were on the edge of starvation.
