Dang, the characters designs and names remind me so much of another manga: "Even Though I'm a Super Timid Noble Girl, I Accepted the Bet From My Cunning Fiancé" (which is a top-tier manga btw highly recommended). Even the FMCs are similarly top of their respective areas of interest/research.
Eh. I guess this just means either that manga was super inspiring, or I know what I like. Who knows?
