Maybe she's a dwarf? Yeah, that works. LMAO I have to agree though, but in the end, it's all fiction. Some of these games, really ridiculous fiction. I don't remember if it was this game or not, but at least one of the father+daughter games I played had t he two get married in the end and I was about dying laughing at how ridiculous it was. I played it out of morbid curiosity but... yeah... I definitely do not play visual novels for how real they are!!!
You can delete the game, but there remains a folder where settings and saved games are store which you may need to delete. Open up your explorer (if on Windows) with Winkey+E. Then in the top browser box, enter "%appdata%\RenPy\OhDaddy-1626454802" (no quotes) and that will take you to the game's folder. You can then delete it entirely, or if you wish to try and preserve your saved games, you can try just deleting the file "persistent" which may help.
