While I don't have much faith in her being actually evil either, I do hope we'll get to see more of Lapis' (dis)organization methods in the future, ADHD Villainess x Overachieving OL is an oddly specific combination I didn't know I needed before.
Anyway despite how generic everything else is, at least their relationship seems interesting, MC is a lovable mess with even lower self-esteem than Gacha luck, and the way the story frames her interactions with Lapis makes it clear Mitori would have clung to her for the simple fact that she gave her a bit of acknowledgement even if the misunderstood, hard-working villainess had happened to be a 100% unambiguously evil person. It's more of a toxic dynamic I would have expected to find in a manga with the "depressing as f*ck" tag honestly, but I'm interested in future developments nonetheless.
