I feel like it might be the 'uptight friend' being the affair partner versus 'man chaser' to subvert expectations or wahtever
Would a male manager giving lingerie to a female coworker be considered sexual harassment?
Considering JP sells vending machine panties (or they used to?) , it is a bit weird even if it's like those cotton multipack walmart has versus something 'sexual looking', i wouldn't even want that from a female coworker versus like "I had a gift card that was about to expire/i don't go to this place usually so i bought these panties but they're not really my thing" and give them to someone else. tho still would rather them being in packaging rather than loose or so grabbed from a bin lol
(tho depends on how expensive underwear is in JP lol)
although it's also awkward to be like "how are things in bed" even to a friend or so lol versus them also being married and bringing it up b/c they have issues with their own husband
I wonder if the coworker knows and is trying to snitch or so. tho it'd prolly just be better to blackmail the husband or whatever depending on the story
