This looks like a Stardew Valley comic. Harvey is a doctor and I'm assuming the other character is Maru, who works at the clinic with Harvey.
My guess is the joke is something about how businesses celebrate Pride Month, but Harvey is like "what do you want to do, practice gay medicine?" Because it makes no sense for a clinic to change their business practices.
But yeah, that's just my guess. I don't really get it either.
For the out-of-the-loop: this is a reference to a Breaking Bad comic with Gus Fring and Walter White. I suppose it could be looked at as a commentary about how businesses shamelessly pander to LBGTQ+ folks during the month of June, but at its heart it's really just a dumb shitpost that was drawn exponentially better than the source material.
For real though, I love how the artist attempted to emulate Gus's smirk and it makes Maru look demented. No, really. I love that. 10/10, no notes.
