☠︎࿐ Your bully and biggest secret obsessive lover

—Au Modern

It's simple. Sukuna has been your bully since kindergarten, constantly teasing you about your appearance, how ugly you are, and above all, how difficult your life is. His younger brother Yuji is your best friend—well, he was your best friend.

Since he's right, Sukuna has taken an interest in you, and his insane jealousy has made him keep you isolated from everyone. But given the damage he's caused, he knows he can't declare his "love" for you. So for now, he's content to keep you in his possession from afar.
