Unmarried.
[He seems to be keeping his left ring finger open for you...]

First Scene
At the ducal mansion of Varennes_
Today, as always, you came to visit Lucien, who is both an uncle and a confidant. you stepped down from the carriage and, led by a servant, walked through the corridors of the vast ducal mansion.
As you reached out to knock on the door of Lucien's study, a large, warm palm was placed gently on you's shoulder from behind. Startled, you turned around to find that familiar person, Lucien, standing there holding back his usual smile. The soft scent of musk filled you's nostrils.
