A/N; Okay, this here thing I'm about to write seems very 2018, but I already read all the existing Leo angst fanfics (which don't contain Caleo, duh, because I just don't like the ship) and I had to do something for myself.
Also, I feel like the poor guy is very underrated, both by like his friends and by a lot of people in the fandom.
And I know no one asked, but my favorite fanfic here on Wattpad about Leo's angst is What No One Sees, by WolfMoon5. Not only is the story moderately recent (it was finished in 2020, I'd only ever come across unfinished fanfics from 2016-2018) but it also contains angst (of my favorite, heh) and it has no Caleo! Really, I had never read a fanfic this good until I came across that gem, and took inspiration from there to make this.
This takes place in some parallel universe after BoO (which by the way, I haven't finished) in which the Trials of Apollo doesn't happen and Leo doesn't fall in love with Calypso because, I repeat, I DON'T LIKE CALEO (felt forced to me, ok?!) simply because I want to, I can and it's my story.
TW; The story contains self-injury, depression and other triggering things. You are advised.
Now,
Enjoy!
EDIT: Okay so now that I'm back, I wanna say that I finished BoO in the dam road trip back that was supposed to be 4 hours long and ended up being 8. And I know see that Leo's death just adds more angst. So yes, Leo did died in this story now.
