Looking for a bl jdrama or kdrama

OKAY, I watched this show in 2021 and I believe it’s a jdrama.
It’s bl, but there’s more subplots. I can’t remember if the guys r roommates or if they’re neighbors in the same apartment.
I genuinely can’t remember much, I recall the main characters like beating up his comforter to dry it??
And I think there’s a het couple in there, and some old folks who live in the complex too.
I think it’s an older jdrama, like 2010-2015
