Reading this gave me an interesting idea for a LN (and If there is one like this tell me because I'd be interested to read it) but instead of being a prostitute she could've taken the isekai'd guy and wrapped him around her finger for max profit. She seems like the kind that could easily mislead a weak virgin guy that seems to idolize her with a bit of cooking, cleaning, sex, and flirting him up like the people in the tavern then when he becomes a big hero because of his cheats just slowly manipulate and mold him into the proper guy she'd want. Two birds with one stone, she becomes super rich and has a guy she raised to her proper tastes and she could even allow a harem because then she could push him off on the other harem girls and deal with him like once a week and still be rolling in cash when he becomes the supreme adventurer. Also that would probably motivate him to push himself as hard as he could to become the best adventurer like how some people will work 60-80 hour weeks to afford to take a woman out to fancy restaurants and buy her all the fanciest dresses/shoes/etc. You could even title it The easy simple sugar daddy hero plan life in another world to keep with the simple descriptive and super long titles jap LNs have.
