i was curious if you had any other headcanons for Will and Nico's sexuality/preferences in your fic!
For Will, he is largely the same way that he is in canon, biromantic bisexual. Rick doesn't really make it clear if he has a preference or not, but I imagine my Will as having a preference towards men!
My Nico differs from canon. He is still gay, solely interested in men, but I imagine him as homoromantic demisexual. He warms up to liking Will quite fast, same as he did with Percy, but when they are older, and getting closer to anything of a sexual nature (which will not happen in my fic!) I think Nico would be a bit more reserved and hesitant, and that he has to have an extremely strong connection with someone before it comes to that. I think this fits really well into the canon of both Rick's PJO and my fic, but I don't really mention it much, since it won't come up in my fic, and also I don't think NICO knows that, or really understands it.
He will (off screen) probably talk to Anteros about it eventually because Anteros is like the LGBTQ guru I swear LMAO
Hope that answered your question enough!
