Summary
You're an office worker living in Ebott, one of few humans who had decided to stay after the monsters emerged a year prior. When asked why on earth you didn't hightail it out of there, you'd say that you, for one, welcomed our new monster overlords.
But despite the jokes, deep down you were excited at the prospects of an entirely new and fantastical species, plain and simple.
One unlucky day as you're caught in the rain with only a bar to seek refuge in, you get introduced to the monsters within: one of which has definitely caught your eye

Summary
Someone thought I should have an Ao3 account so that my work easier to find, so here it is. Note that unless stated otherwise, these are written by me. Also for these stories, despite covering chara x reader (self-insert into Anon, it is short for Anonymous), they're mostly self-contained, think like most cartoons with the status quo resetting at each episode most of the time, will note when a story is a sequel to previous story.
Also will note to not expect new greens/chapters for either this or my NSFW archive in a consistent matter, this is mostly a side thing I do when the brainworms say that I should do it because my obsession with Chara is too strong and if I don't write some of these plots, who will? My main hobby's videogames, I do see the "kudos" (what the website calls the likes) and glad that you were able to enjoy these greens in some way or another.
