Sort of Scott Pilgrim heartshipping au that may or may not end up with yuumeishipping
So. Yugi finally gathers the courage to ask his crush, Ryou the weirdo, out who amazingly says yes! Yugi's super happy! The very next day, Yugi takes Ryou out for a fun gamer date, which somehow ends up leading them to hang out in a forest at night after a quick dinner. Yugi is a little jumpy, but Ryou holds his hand and tells him stupid stories about why the monsters in the forest won't hurt them ("oh, don't worry the creaking is just Sato. He's a vegan, so he won't eat you." "Yep, that's my ex Kaonashi, he's all bark and no bite. He's probably just jealous I have a cute date." "Did you hear that? That's probably the tengu I went out with last month. He had a really bad morning breath."). Yugi kind of laughs along at how ridiculous the things Ryou is saying are, and it actually ends up putting him at ease in a weird way.
HOWEVER. As they're about to get a little romantic, Yugi suddenly gets jumped by an actual monster! Ryou manages to ward it off and after Yugi calms down he explains to him that he did actually date all the things he joked about at one point and that Yugi got beaten up by one of his newer exes, some blood demon with an inpronouncable name (it's Yamima). Ryou also confesses that all of his human dates eventually end up being chased off or killed by all the demons he's had history with, and he asks Yugi if that would deter him from pursuing him. Yugi puffs out his chest and says "no, it wouldn't" because despite only being on one date, they've already been friends for some time, and Yugi REALLY likes Ryou. He even screams a challenge to all the demons who refuse to move on from Ryou. Ryou finds it endearing, and they leave the forest and part ways on very positive terms.
MEANWHILE back in the forest! Yamima returns to a mysterious camp (the leuge of evil exes) and tells all the other exes there that he's failed to eat Ryou's new potential bf. And that he got decked by Ryou. And Yugi's challenge. So the leader of the evil exes (Zorc probably) decides that they will all try to kill Yugi, and whoever succeeds gets Ryou for themselves. The other evil exes are pumped, and they prepare for murder.
Over the next few weeks/months, as Ryou and Yugi grow closer together, one of Ryou's main evil exes show up and try to eliminate Yugi, but Yugi and Ryou somehow always prevail (it's the power of love babeyyyyy).

- Bakura, a ritual game bound demon
- Seto, the vengeful spirit of a samurai who thinks Ryou is the reincarnation of his dead lover (he is not)
- Ryuji, a clown/jester zombie thing with a gambling problem
- And Zorc, the dragon dick demon (idk)
There is also Pharaoh Atem, some sort of undead mummy thing, but he's never actually dated Ryou before. He gets brought into the picture by Kaure, who offers Yugi to him as a potential undead consort if he successfully traps him and lets Kaure deal the finishing blow. Despite everything, Atem would still be the first to join the weird ass polycule.
Some evil exes move on from Ryou, some assimilate into the Ryou/Yugi harem, and by the end of it all, Ryou and Yugi have a whole monster army to stop Zorc from doing Zorc things.
They all live/exist/die happily ever after! (Except for Zorc) The End! 🙃
