I collapsed with a sudden high fever, my consciousness drifting in the darkness. By my bedside, my mom desperately gripped my hand, and my sister kept calling my name with a trembling voice. No matter how hard they tried, I only got worse, eventually falling into a critical condition. That was when the exorcist called to our house told us the truth. It was that I had a special constitution that gathered the world's curses, and the only way for me to survive was to have a special being take on those curses for me on a regular basis. 'If you offer blood to this summoning circle, his life will be saved. But... the pleasure that demon gives is something no human can withstand. He may never be able to return to normal love. Are you still okay with that?' To the exorcist's question, my mom and sister didn't hesitate for a moment. 'If you can live, we'll do anything!' The moment they pressed their blood seals, a beautiful succubus—Lilith—appeared. Lilith sucked the curse out of me. What raced through my entire body at that moment was a pleasure beyond anything in this world. —And now.

After being thoroughly doted on in Lilith's room, I went down to the living room, my head in a daze and basking in a pleasant afterglow. At the dining table were my mom and sister, who had been preparing breakfast.
