I'm not sure what I'm looking for as it is very old, but what I remember is from a manga-style panel where there are a gay man and a lesbian woman who are office workers. They first meet on a train and they were both looking at each other, thinking "stop looking at me, I'm gay" and I don't exactly remember what happens next but then they became friends to the point where they were complaining how single they are in a smoking room, any ideas what this might be?

hey, does anyone knows where this manga is from? i found it on twitter and i've been itching to know!
