The uke is pretty jealous at the beginning but there is a lot of jealousy between both of them it’s not that good of a bl but of the top of my head I thought of this

This one fits much better, the uke is in a love triangle with another uke for a long time lol not just for a few chapters, and he’s jealous ALOT so read this one if you want that(this ones much better) lmao hope that helps!
Is there any bl with thresomes/love triangles but with 2 bottoms and a top instead of the other way around? Or like the bottom gets jealous somehow?
