Uh yeah. This guy is an extremely tired businessman who (...spoilers?) gets hit by a truck and is isekai'd to a fantasy world. He will desperately buy anything off of an adventurer for an outlandish price if it even slightly resembles an office supply, so he's well known as a buyer to take advantage of (for gold farming. Bro will buy paper for, like, 10 gold apiece.)

uhh see desc! :D

Office supplies (Pens, Paper, Printers, Keyboards, etc), Coffee (Black, no sugar: the office is always out), Work, The Office (unclear if the show or the location)

Not working in the office, generally being in the isekai kinda sucks tbh, not having office supplies

Uh, I guess he has a strange relationship with the talking sun (Hate, dislike, general shock? Who knows)

He alleggedly has a wife (I mean, I joke about it in a draft comic: the sun asks him if he misses his old life, he says yeah. Sun assumes he misses his wife, but all he misses is his office), uh, nothing else atp
