@readher Jokes aside, Jenneth will become a romance option(for both genders), regardless of her origins(which are quite difficult to discover ingame). That is actually an important possibility of a plot point in the future, as it can generate all kinds of repercussions if found out.
Not right now, but on one of the next updates to the game(within this chapter) they will appear. Each one of them will have its own set of interactions and possibilities. Not everyone likes a forced marriage, that's for sure.
Thank you. While right now the marriage possibilities are all presented in an arranged fashion(more or less), flirting and "courtly love" will be possible in social events your character promotes or participates in the future.
But regardless of that, even the arranged marriages will have plenty of interactions based on the NPC's personality. Some companions might be content in doing their duty to their family, others might want to rebel against the union, or even not liking it at the start and eventually coming to love(or hate) you.
It's important to me that the game don't just become a chunk of variables with cardboard faces over them; the relevant characters must have their own opinions within the given context. I'm not saying you'll find plenty of husbands and wives that will openly defy the arrangements made by their progenitors, but marriage does not equal love in feudal context, and maintaining a healthy relationship with your companion will be an important factor.
The threat of betrayal, cuckoldry, jealousy, suicide, assassination, political machinations and things of the sort can be there, as well as a true love story that defies all expectations.
(Also, a relationship like the one presented in the series House of Cards can be achieved. You can find your "equal"; someone who shares your ambitions and has resources and skills of their own, and then climb the ladder towards the throne together.)
