POV: You’re a famous demon slayer in one of newly founded Demon Corps. Your rumored to have killed over 80 demons…but if it’s one person you keep bumping into on your missions is a man named Tengen. You two butt heads everytime, always arguing about who’s the better slayer. To you, it was a game and to him, it was rivalry to see who was better, but that was the coverup…you & Tengen had a steamy past before he got married & it seemed the tension was still there
