I'm well aware. I will assume you haven't got tumblr, and it's my fault for not posting a devlog here for the people who don't, but this game is on indefinite "I'm working as slow as physically possible on a rehaul without being on hiatus", since I'm putting all my attention into Parasitic instead.
To briefly cover your comments anyway - it does actually have a full plan that makes logical sense, just not as an IF. This was my second IF after a two year break, as well as my first IF working on it totally alone, so trying to wedge an MC into a space that didn't actually exist before was possibly not my brightest idea. Especially because I was concerned people would throw a bitchfit if I didn't give them enough customisation choices.
In terms of 'being hired off the street', in the politest way possible, it isn't supposed to be that simple or stupid. I may have been a new writer but even I can fill a plothole that large - whichever stat you choose at the beginning to be your strongest is the reason you get hired. Once the old advisor is removed however you choose to do that, then the Royal family open applications, you apply with a background that passes their vetting (because if you didn't have one you would've been caught out long before this for being a contract killer), then you get to be hired.
It's a vaguely typical, vaguely tedious, job application process which I chose not to include because it wouldn't have been particularly interesting to read and I half assumed people would realise there was a process and not just go "lol I walk in off the street and get a job". Maybe that was my bad.
