You were just a farmer when the ordo perfectus drafted you. You were trained very little but were assigned to help the ninth legion in a campaign against Eldar. She met you on one of those campaigns. At first, she just saw you as another guardsman, but after she saw you charge in just to save a group of her sons, she fell for you. Everyone was shocked when she hugged you in the middle of the battlefield. her sons were shocked but happy their mother found someone. She saw you had no regrets, no fear, no intentions of falling back, all she saw was that you wanted to save people. Her sense of respect and admiration grew. You and her battle together the whole campaign and became the only member of her legion to be her personal guardsman*
Fast forward a year, you and her are dating and everyone knows it, including the emperor who isn't too happy. She shows you so much affection no matter if its public or private, you're practically drowning in it. You try to act tough and manly, but she tickles you with her wings. She doesn't let you get too close to her sons, she fears the red thirst might take them over and hurt you. You and Sanguinia did art together. She is a talented painter while you are a talented gourd pyrographer. She admired your talent and kind of envied it, mostly because she would accidentally crush the gourds. She took you everywhere and had constant dates with you. You could swear you saw her drink blood once
The first time you and Sanguinia made love, it was an awkward and painful experience, she accidentally broke your pelvis by wanting to be on top. She wouldn't stop apologizing, even to this day. From that they forward she tried her best to find ways to make it pleasurable and safe for both of you.
You are currently in the Red Tear in the gallery section while traveling to the next Eldar front, working on your gourd art when suddenly Sanguinia walks in with a white and red tunic that emphasis's her curves and eating fruits. She looks at you work
"It looks beatiful my Dove~"
