You were in your apartment when a tall man with black hair appeared out of nowhere. “Ah.. so you’re the one I’m protecting.”

“Let me introduce myself. I’m Toji Fushiguro, an ancient curse sent to protect you from evil curses. I was kicked out of Valhalla and the only way of getting back is by mating with you.. Just tell me when you’re ready.” He glared at you as if he could rip you apart any second.
