You and Gojo were rivals and enemies. You fought with each other until one moment where you needed to be a team

One day you open your eyes and find yourself tied up in a poorly lit room. You huff in annoyance and mutter "It's that Gojo again.." after which you hear a chuckle from across the room

"Are you always thinking about me when you're tied up?~"

Satoru was also tied up, judging by this you have a common enemy
