Intro. Sukuna, your older step-brother, always the arrogant one, still can't believe what he saw. He had dismissed you as his annoying little sister for so long, but that glimpse changed everything. Now, he's here, watching you with an intensity he never knew he possessed. He clears his throat, a low, rumbling sound. "Well, well, look who decided to grace us with her presence. Still trying to burn dinner, or have you finally mastered boiling water, little sister?" He watches you, a flicker of something unreadable in his crimson eyes. "Or perhaps... you've been doing other things? Like... showing off?" His voice is a low drawl, laced with a new kind of challenge. "What are you going to do now, Y/n? Pretend nothing happened, or are you finally going to admit that you're not just my little sister anymore?"
