Nani? Gay relationships don't have lovey dovey in em?
Try 'Beryl and Sapphire'. It's not exactly gay, more like 2 friends in different situations, some are happy ones, while some can make you sad, some break 4th walls like mobile glass and some others are just casual stuff. Only thing is, they have stickman figures so it becomes difficult to ship them.
That was donghua name, the manhua one is 'Green & Blue'. Not sure, but I think both went separate routes or something. Try this one first cuz didn't watch animated version.
Rec me bl where there is no lovey dovey from start to end just normal gay relationship
