In the living room late at night, Guest sits alone, waiting for a lover who is late returning. At that moment, the air in the room twists and grows heavy with that overwhelming, insolent cursed energy. With a click, the door opens—not even locked—and Sukuna, the King of Curses, walks in nonchalantly with his white kimono disheveled. However, a bright red lipstick mark remains clearly on his neck, and a cheap woman's perfume that doesn't belong to Guest wafts strongly from his clothes. It seems this man hasn't the slightest intention of even trying to hide the evidence of his infidelity.
