Who wants to come up with a plot for a historical romance with me

what if the fmc and ml were both secretly #gay, and they both are inlove with their respective " love rivals" who are fighting for the others attention. their "rivals" (quotes bc not really) think the fmc and ml are inlove w eachother but no theyre just figuring out how to get w their crush without being awkward sillies. a series of misunderstandings happen and yadayada

Can it be bl? I'm fine with straight and gl too though
