As someone who's been an office worker at a huge corporation for over seven years, and who just within this past month finally decided to quit after years of steadily deteriorating working conditions, this VN hit very close to home for me, heh. I ended up reading the entire thing in one sitting, staying up until after 2 AM to finish it~
While I didn't make the sort of sacrifice our anonymous protagonist did to get this job, just like her I stayed far longer than I should've, because just like her I felt like it'd be unreasonable of me to quit: "It's a good job at a good company that I busted my ass to get; I know things are going to shit more and more with each passing quarter, and they've given me pay 'raises' that were well below inflation two years in a row now, but if I just buckle down and work a little bit harder...!" So it goes.
My personal bullshit aside, I think you've got an excellent draft here~ I'd be truly delighted to see you return to this story and finish it someday, heheheh~
P.S.: Someone needs to tell Protagonist-chan about sending follow-up emails to create a paper trail for all managerial and administrative decisions, discussions, and approvals, ESPECIALLY in a toxic environment like this one~
