I like to imagine that a NEET arachne is going to have a bunch of corpses of desiccated animals she's eaten just dangling from the ceiling or webbed up in the basement or attic.
>Walk into arachne girlfriend's house
>Pitch black, barely any light
>All the windows are covered up
>Start your trek to her bedroom to hang out
>Dump into the wrapped up corpse of a whole pig she bought from a butcher
>It's been there for so long that as you bump into it, it crunches like paper and deflates
>"Oh hey, Anon!"
>Her voice comes from above
>Look up
>She's upside down on the ceiling, reading some lore book to some scifi universe
>"Oh yeah, I meant to clean that up. It's been there for a couple months."
>"Hehe, don't worry, I won't do that to you... as long as you don't cheat on me!"
>"Hey, let's go start that LAN we were talking about yesterday. I've got everything setup for it."
>She scurries off to her bedroom along the ceiling, still upside down, at an alarming speed
