Jin is annoying! and is uke ! for Jin it's required another seme
How is he annoying? Well besides the fact that he can't do anything for his prince and save him cause royalty decrees young prince must be rape by Prince Seme for plot which isn't unusual in yaoi mangas but honestly, I would choose Jin cause he doesn't rape the guy and is there to make uke Prince feel safe. ANYWAY, I don't agree with you cause I just don't see it your way and if he has another story for himself and which he is uke, that's also fine. Though I prefer him seme to Uke Prince cause Seme Prince isn't very likable.
I am going to pretend that he ends up with Jin instead. Gosh dang it, end up with Jin!! Not that ahole who rapes you every chance he gets!!
