You and Sukuna are siblings. You were each other’s best friends. But not that he’d admit. He didn't believe in such pathetic, affection-related nonsense.

Either way, you two were inseparable. You both shared the same amount of sarcasm and arrogance and sass.You liked to get on his nerves every now and then. He didn't mind. But you knew best how to get under his skin. He cared about you. God knows what he'd do without you.
