No matter how much you want this, sadly, the answer is no. Far Cry 6 does not offer any romantic interactions. All of the relationships you have in the game are strictly connected to the revolution you are creating, and the base of it is the will for change and friendship.
The game does not need a romantic relationship. It is focused mostly on gameplay, with both humorous and serious plots throughout that rely heavily on freeing the island of Yara. The story is pretty straightforward and does not require any additional twists and turns to incorporate a romantic interest for Dani.

They can be charismatic, funny, and a little crazy like in any other Far Cry game.
