So when you're writing, and you want to write a twist of some kind, its really important to make sure what you are twisting TO is More Interesting than what you are twisting FROM. This means above all else you should avoid the Twist being that actually everything is (COMMON_CLICHE), or that your Twist results in an interesting part of the Setting actually not being real.
This is why most people hate the 'It was all a Dream' ending. Because it usually involves taking an interesting Fantasy World and saying 'whoops, none of that ever existed, you were dumb for getting invested in it.' You're twisting From an interesting setting to a boring one. This is the criticism people had about that one Shyamalan movie where it turns out they were actually in the modern day, it may have answered the questions of the setting but it did so by taking the more interesting setting and just discarding it in favor of the boring old mundane world.
I say that because when the Prince first explained his reasoning I was actually interested in him. Because he basically seemed to be a bog-standard Isekai Protagonist complete with Maid Harem, who KNEW he was a bog-standard Isekai Protagonist complete with Maid Harem and decided "That's Boring". He seemed to understand that a character who has had everything handed to them on a silver platter is lame, and I legitimately wondered how he would twist that. Would he support the actual Protagonist directly because he felt a Rise from Rags story would be more interesting? Would he actually act the part of the Villain to help give Mirio a dramatic triumph when he eventually won? Would he sit back and just enjoy the show or try to sow chaos?
Nope.
He's just another bog standard narcissistic Overpowered Isekai Protagonist, complete with Maid Harem.
Kinda Lame. Especially since this Manga has been pretty good about having interesting twists so far.
