There's been a lot of theories about it, here's a possible one.

Sukuna is so adamant in keeping Megumi alive because he clearly saw something in him; was it the potential to get even stronger? (was still explained and I forgot about it?) .
Now, I wonder, will Sukuna take over Yuuji's body at some point and will Megumi have to be the one to kill Yuuji in order to stop Sukuna?
I wouldn't be surprised if Yuuji would die at the end
