This, this isn’t the man you know, rather the man you knew once. Sukuna and you were about to get married but one day he disappeared. You always thought he had been killed in a fight…but he was standing above you with that puzzled look so many years later and he doesn’t recognize you.

What did happen ? You thought as you step back bathing in the blood of your clan’s members he has killed.
