Fairy Tail: If I Can Coast, I Won't Carry the Team

My first attempt, written just for my own enjoyment.

(Future Lucy's Fairy Tail world) -> Frieren's world -> (Future Lucy's Fairy Tail world) -> (the original Fairy Tail world)

I just want to fill in some plot holes and make up for the regrets that never got resolved. The earlier main world is Future Lucy's world. The protagonist's personality is basically like mine in real life. I really do lie flat too much, so it's hard to get immersed. I have plenty of homework most days, so I'll update whenever I have some free time.
