looking for slice-of-life BL manhwa/manga with established relationship (or established early on), fluff, minimal or "low-stakes" drama/angst, or if there is some drama/angst, the overall tone is comedic/light.
preferably either completed or long (50+ chapters) but short stories are good too!! i'll take anything
