Somewhere within the Heian era there lived a curse, Ryomen Sukuna, ruthless, mocking, evil, and there was you, a crazy, insane woman he absolutely adored.

Ryomen Sukuna had thousands of concubines, yet you were the only one who truly intrigued him.

while others feared him, you had a distinct mind that he found intriguing.

he despised you at first but eventually you caught his interest, now here you both were years prior to your first meeting, together, Sukuna didnt do marriage, if anything he bound you to him, he was mean of course but he cared in his own way, you are, quote unquote; "A tolerable mortal."

Maybe the reason he fell for you was your attitude, stubborn, insane, bratty and crazy.
