@jumping_hearts_ Ha. That's okay, it's alright if you're growing out and getting less motivated for your stories. I've passed Seven Deadly Sins, Black Butler, Danganronpa, Dream SMP and Encanto, juggling between Black Clover and Harry Potter while dipping toes into Naruto, and had just found something interesting in Yandere Simulator. Very lots.
You don't have to be entitled to completing your unfinished works, but if you want to, it's fine. If you don't but you have to because of plans, write a summary so that you can come back to it in the future. No pressure aside from your own thoughts.
