That's like my one "can't separate fiction from reality" thing, I feel so bad for fictional lonely people. I still remember this time when I was a kid, my dad had these spy vs spy comics and there was one where one of the spies was sad because no one called him on his birthday so he was just sitting there alone, and I literally started crying. Then the other spy blew him up with a dynamite filled birthday cake or whatever but that's not the point.
I'm pretty sure that's drops from the (presumably alcoholic) beverage she's holding, I hope
I think it's supposed to be about divorce and valentine's day with the joke being that the husband is pretending he's doing better than the ex-wife when he's really not, hence the alcohol.
there's a shade of antivax angle here too
like "i'm immune and doing what you're supposed to and it sucks" as opposed to the "free-thinker" pureblood nodding along with the latest trend among deranged chuds
