Bankrolling a failing politician for his election is profitable due to the exceptions granted to their company although shady, this series doesn't shy away from forcing its rules despite it not making any sense with the theme aesthetic. Rules such as they have a printing press capable of printing images and text at the same time. Why? Magic. They can get a video recording as well. How? Magic. The author can just makes it so that claiming the investment is just par for the course in this society ergo this world's rule. Another reason for the engagement is so the company has a better grip at that seat of power despite it being small, giving them an advantage in market competition and possible connections to other governmental positions. This way the protagonist will remain proactive with the power she's given while retaining the moronic demeanor of the fiancee.
But here's a better solution: have the structure of nobility with modern technology. It's not far-fetched and given what I've seen thus far, that seems to be the case. Author gets high-tech whenever it wants to with the excuse of magic. Seems uninspired and really just wants to force it in. Won't be surprised if it pulls a Breath Of The Wild and whip up a smartphone analog.
