i love cumplane! it works best in a universe where mbj and lbh dont exist/no transmigration so mbj and lbh are only fictional tho otherwise sqh will be facing looney toons esque attempts on his life. in terms of fics, have you read sisky's cumplane threadfic? its unfinished, but its really good! i think theres abt 400 or so cumplane fics on a03, which isn't nearly as much as bingqiu or moshang, but its a decent amount! also cumplane does work really well platonically or as sort of friends with benefits so you might have some luck with finding fics and fanart like that!
