Would be cool if MC over the plot of the game ends up improving himself
Ideas for dev to swipe if they want:
Secretary helps him become more diligent, take learning things more seriously and management of finance, tutoring scenes with "rewards" etc.
Cook makes him more interested in refined behavior, maybe scenes where she drills him in table etiquette, manners, etc (again rewards, maybe some content in kitchen, when mess happens in kitchen = first shower content, leading to the other two peeking = unlocking their shower content), maybe lactation content, maybe not.
Maid teaches him about hygiene/exercise, about the work done around the mansion (pool/outdoor content).
In the end Dad is literal chad looking out for his son to refine him into a successful heir through these three as the plan all along, which is kind of the vibe I got at start with the Dad seemingly looking out for him.
Wholesome content with butler training MC to learn how to fight (butler is comedic relief of being jacked old man akin to roshi, and is actually trope of also being a bodyguard the whole time). Dad mentoring MC on other things as small short side scenes.
