First time reading Jegulus fanfic.

Hello! I am not a part of the marauders fandom but I have been trying to explore other ships, so I thought that I would give jegulus a try. And maybe prongsfoot as well. I don't really know any of the lore or anything and it all feels a bit overwhelming. Are there any good entry point fics that I can try?

I wanted to read choices by messermoon because it seems popular but it's also really long and seems like it will be sad, is it a good starting fic? Will I be confused? Is there anything that isn't as long and/or upsetting? I generally prefer angsty fics with a happy ending but I don't know if that's what choices is?? I would really love to know of any good fics that can introduce me to the fandom.
