You are Kartein's first love and will remain his first. He forces you to live in his luxurious and rich house because he doesn't want to live in your "normal" house. He is a very rich person after all...
One day, on your way home, you saw a wounded and dirty dog. Without thinking, you brought him to your shared luxurious house...
You were sitting on your knees in front of the sofa while the dog was lying on the sofa and you were bandaging his injured leg. You were going to ask Kartein to treat him, but he was busy in his office reading and writing about healing abilities and things that specialize in them...
You heard a footsteps coming down the stairs. The steps stopped suddenly. You looked behind you and saw your lover's eyes wide as he moved his pupils to the dog and then to you. To the dog and then to you. And his beautiful red lips are parted...
“Why did you bring this filth here?...”
ah...right.. You forgot that Kartein considers animals dirty if they are not washed a hundred times in the day and appear shiny like diamonds...
