Sukuna said he was "interesting" but not in a gay way more in a potential fighting buddy way. Like Sukuna's so powerful that not many people let alone curses can fight him one on one. BUT he sees something in Fushiguro and thinks that if he give Fushi some more time he'll grow strong and be able to fight Sukuna one on one.

-Sukuna said “don’t die, I need you to do something”
- And when He made contract with Yuuji, he said “We will see something fun/interesting” with the background of Megumi but he made the contract that he can’t hurt or kill anyone which means he can’t fight Megumi in that one min.
-He told Jogo that he had his own plan.
So I think aside from Potential and talents, Megumi might be VERY important to his plan, maybe if Megumi dies the plan might failed.
There are many theories about Sukuna’s plan, and I think what possible is he want to resurrect himself or he want to make a mess of the world like... the war between curses and humans.
Any theories to why sukuna is saving fushiguro?
