Did you pay attention to the game??? or the steam summary???
As you don't recall me from previous discussions, it is not me who struggles with paying attention.
The True end deserved ATLEAST a CG of her and prince as that is her main goal from the start of the game (well to stay pure for him etc... you can tell she already loved him lol)
Nope, the main goal of the game is to restore order and discipline in the most lenient prison in the grand empire. The game starts not with a romantic date but a working visit to this correctional facility. Karryn's initial relationship with the Emperor is strictly professional. It is rather the Emperor who's referring to her as 'my beautiful secretary' than the other way around, herself using any terms of endearment. She's only performing her duties as a secretary.
She's even seriously offended when Yasu makes an innuendo regarding her career as His Majesty's personal assistant. This serves not only to portray her as a total noob when it comes to all things romantic, but also as a conceited snob obsessed with her own professionalism.... who's about to have her mindset rewired. She initially rejects Yasu's idea of her becoming the new Warden ('not proper work for an elite like me!!!') and eventually takes the position when both the men pull a fast one on her arrogance. 'I'm incapable...?', she says. And thus begins the life of Karryn, who grew to fame as the Imperial Secretary...
As for her true feelings towards the Emperor...
Yep, you're the one not paying attention.
Happy Ending is just as Anticlimatic as the Empress Ending, so dunno what you are talking about.
That's because the lv 5 defeat scene is the apex of debauchery. Plus lower level defeat scenes also raise the bar, so redressed bed scene you can get on Day 1 has not been the most generous slutty reward. They could have rearranged these scenes better and prepare a Happy Ending that would have topped lv 5 defeat orgy.
