If you want to see most of the cast, here it is.
If anyone doubts this is the spawn of Tumblr, the dot points that represent each of these people backstories are the smoking gun. They're based on
Tag Yourself Memes, a low-effort Reblog-farming tactic.
Even in that context, it's an immensely stupid way to present it. The Tag yourself meme is meant to be extremely generic and relatable, like a horoscope, so it applies to the most people possible with the fewest options. Trying to turn that into a substitute for a character backstory requires making it extremely specific to the person, which ruins half the point of the bloody thing. I've also got no idea whether half of these are meant to be from the character's perspective or not.
Take Emhari Abdi, for example.
I have no idea whether these two oh-so-relatable points are meant the be her/him's views, or general statements meant to refer to them. It might be both their views, in which case they're a snippy individual but nothing too far out of dating sim land. It might be they're referring to the character from an external point, in which case they honestly a bit of a drama queen. Or it might be that one is their perspective and one is their character, because fuck consistency. You genuinely don't know.
Another one that stuck out was the Marriage Counselor who's every quote is like 'marriage is overrated and fuck romance' while secretly yearning for it. That... makes them a bad marriage counselor? Why would you have someone who hates marriage take the role of someone who is meant to help stabilize or peacefully put to rest struggling marriages? It makes them sound like they sabotage savable situations because they're lonely.
compare with a randomly-selected character sheet from Cucumber Quest:
It sneaks jokes in, it gives a sense of her personality, it introduces her pronouns (because you can just do that organically if you're not an idiot about it) it gives a sense of how she fights through her stats, and it really covers all the basics for her. And this is a webcomic, not a visual novel. It's not a good sign when the visual novel doesn't lead with their actual prose writing chops.
