Any fandoms I should get into that has many djs? Preferably one with many ships like blue ...

ensemble stars

Haikyuu, boku no hero, slam dunk

if you're reading on mrm, there's a series and ships masterlist at the very bottom that shows you how many works are under a fandom or ship so that's probably a good place to start

Gintama. Specifically the Ginhiji ship (my otp) has a fuck ton of djs

Thanks yalll!
