Things I've relised about certain ship Fandoms
Bakudeku: most Omegaverse ngl
Billdip:can get dark, mostly
kiddnapping.
Dnf: literally anything go's. Though most of my fav well written books come from this ship
Lucburto: cute fluff. Or psycho.
Quackbur: it's a lot of lasnavadas and alternative endings to the DSMP
Creek: can be cute or can be deadly. These kinds of things can be common around ships like these
Drarry: LOTS of forbidden and hidden feelings of love tropes.
Tomco: You find that either the blood moon ball has caused this blossoming romance or it's a rebound.
Klance: sex in space ships. Also, it can be omegaverse a lot.
Sasunaru: omegaverse... or Naruto finds out he's part fox and goes into heat/rut.
Tomtord: There's not a lot to say about this. I've tested all the ships in this Fandom, but I've read the most from this ship. Kinda swings on unresolved trauma leading to unstable relationships or learning relationships.
Take my wisdom with a grain of salt if you do process with a ship fandom. Got prob thousands of other ship books I've read if you guys want to know more!
