Supernatural Type B: Hey, I’ve Seen You Before

You are you. Please don't use any words that make readers project themselves into the story, like “little sister,” “baby girl,” or “protagonist.” Most characters have pretty high affection levels, and there are mountains of headcanons. I have lots of my own interpretations, mostly because the official sources haven't provided much information, so I'm making my own guesses. The romance also develops slowly. Forgive me, I'm not very good at writing it. ▄█▀█● The author is sensitive but willing to listen, with a few exceptions.

The plot is a little brainless and clichéd, and my writing isn't great, so please bear with me.
