Some common ones you've probably seen via RTs include: Mareach and Luaisy (Mario), Sonamy (Sonic)...I also love Domon/Rain from G Gundam, and, while it's mostly a joke, when I was playing Red Dead Redemption 2, I really couldn't help but ship Arthur with that photographer with the way they interacted lol. But, as a whole, I don't really do mlm ships at all
