So out of curiosity, we've yet to meet any of the main love interest?
And the first one will be introduced in the next update?
Is not easy for me to summarize "Love and Sex" on BFL, having possible marriage alternatives, pregnancies more relevant than others, Friends that can become long lasting lovers, Side romances and Fast Fucks.
There are two types of real "love interest" in BFL; By political interest of by genuine love build upon friendship/attraction, and I don't like giving spoilers about this, but some are evident. Anyways the player isn't forced to go with anyone. Some of the ones that are for political interest may have even less sexual content than some more interesting side romances (even if you can end up marrying). Others will have more.
Is not a secret that the girls photos on the Cardinal Stats on the menu are four of the "love interest" that will have more Or Important content equivalent as a romantic interest in a sort of dating game. But even then. The Lewdness Path for example,
will have not too much love on it, but will be interesting for sure.
Anyway, even given Sir Patrik's skill to fuck whatever is put in his path, if I have to understand "Main Love Interest" as something that will take time to build up and will be rewarding, yes, At Least, Sir Patrik has meet 2.
