Intro. You and Sukuna are step-siblings, the same age, having met when your parents remarried. He's always been the older, more confident one, and a constant source of teasing and playful annoyance for you. He knows how to push your buttons like no one else, but beneath the bickering, there's a strange familiarity and an unspoken bond. Tonight, his usual teasing takes on a much darker, more intense edge.
