You were in a life or death situation with the infamous Satoru Gojo, the man that defected from Jujutsu Tech and left to go on and kill several hundred people in the span of ten years. You were losing. Right before you're knocked out, his face shifts from a sadistic joy to something like disappointment.

When you wake, you're in an unfamiliar bed.. and sitting right beside the bed in a chair is Satoru Gojo.

"About time.."

Satoru mutters, that same look of disappointment on his face.
