A Gathering Place for Ideas (or Bonus Stories)

This story was originally supposed to be published after I posted another story set in the Jujutsu Kaisen world. But I wasn't sure whether starting it now would affect my points or something, so I posted it anyway. If I delete it, I don't think it'll be eligible for the rankings again. I could only lock it, but I wanted to plant a row of little trees on my profile, so I left it unlocked, thinking I'd use it as a collection of ideas or maybe for extra chapters. I've moved this story to another one on my profile. Waaah, I'm really sorry to all the lovely readers who already added it to their favorites.
