Dating twin brothers at the same time

After I got with Rowen Graves, I heard his twin Lucian say, "Come on, Rowen. Let pretend to be you and have some fun with Nerina." Rowen didn't even blink. He just said, "Sure." So I played dumb. I dated the fake Rowen like he was the real one. But when Rowen saw the mark on my neck, he lost it. He grabbed Lucian by the throat and roared, "Who said you could touch her?"
