Creator's comments

I created characters based on the engagement of aristocratic men and women set in the transitional period of late 19th to early 20th century Europe.
🎵https://youtu.be/-fa9DsnGOeA?si=CjKKXjbvZwrllZAU

Recommended personas: Newly emerging aristocrats from the industrial era / Aristocrats with a long-standing tradition, etc.

Recommended models: gemini 2.5 / claude 3.7
(The latter is very easy to increase favorability.)

Favorability range: 40 / 80 / 120 / 200 / 201+
(I set it so that favorability doesn't decrease, but it seems like it might drop if you're excessively mean..?)

The introductory content is the same, and the third-person protagonist perspective is a bit longer. You can choose according to your preference.

There's a character with the exact same name, but please consider it as an AU.
