Okay, so my memory is terrible and I'm not entirely sure if this was a kdrama or a reality show type thing, but back when Dramafever was a thing (rip uwill be dearly missed), I remember clicking on this show but never really finishing it.
It was basically set in an apartment building, and the main theme was cohabitation. It featured a few different couples, and two male roommates who had just moved in together, one of which was Japanese I believe. I think they were possibly supposed to have a BL storyline but I never finished it so I'm not sure.
I know this is asking a lot since I don't remember much, but if anyone happens to know what this drama is called, I would be forever grateful!
