Heh, I noticed already that you are not a romantic, your way of treating women disgusts me, let me explain:
At first, I thought it was funny that Selena looks like Zelda and she is shocked when the hero speaks because "the prophecy foretold of a silent hero who saves the kingdom and never speaks a word", just like Link in The Legend of Zelda, I understood the joke and I found it funny. 😏
But then, the hero started being selfish and creepy, blackmailing and coercing the princess to have his way with her, I hated it! 😣
It's a shame because as I said, we all have been frustrated to play games who make us brave countless dangers to save the princess and not get the girl in the end and you could have exploited this frustration to develop a funny story with your princess who you designed to look like Zelda and the hero who is a gamer who has already saved countless princesses and worlds in video-games and is fed up to never get the girl because these games are for "all public".
You could have made the first encounter between the hero and Selena go like this for example:
Selena: "Oh, noble hero of legends, you came in our time of need just as the prophecies foretold, you are going to battle the countless armies of bloodthirsty monsters all by yourself and save my kingdom alone while my guards stay safe in the city!"
Hero: "Wait what? Oh no, you don't, I played enough games to know where this is going and I'm not saving one more frigid princess if I don't get her in the end! If I risk my life to save your kingdom then you're going to reward me properly as a princess should reward her hero!"
Something like that instead of "Show me your tits or good luck saving your town without my help" which is not funny, it is merely creepy.
Intimacy is a reward which loses all meaning if it is coerced because it is no more a reward then if it is forced and therefore doesn't feel rewarding at all. 😒
You could have developed a growing intimate relationship between the princess and her hero in which the hero doesn't blackmail and coerce her, he would seduce her instead, asking for dates as incentives for his hard work and doing his best during these dates to conquer the princess' heart, that would feel so much more satisfying than coercing her like a rapist.
That is, if you actually bothered to offer an actual story with actual character development instead of your lame excuse of a "plot" to justify sexual adventures in an isekai where your characters have no depth at all because they are all mere generic characters, a gamer turned actual hero, a devoted princess, a tsundere royal guard, a greedy shop owner, a sort of goddess who watches over worlds, a shady merchant who sells shady services, a bad guy with tentacles, they are all unoriginal generic characters already overused and you didn't even bother to offer them an actual personal story, they are just here to fulfill their role and that's it, they have no depth at all, just like everything else in your empty "story".
