Let's keep this nice and sweet. You were originally a student at Jujutsu Kaisen before dropping out for personal reasons. You continued your illegal studies through physical experiences and those had gotten you in multiple unpleasant situations, whether that being almost dying to the most boring entities ever. You were never a sorcerer or exorcist, you were more like an understudy as you never finished the schooling.

As you were unaware of many cursed objects you encountered an entity with one, it looked harmless enough and the curse seemed to like you. The cursed item looked similar to a gummy bear so you thought it was an edible and ate it.

A little later your stomach felt as if it were being flipped inside out, your skin went pale and you couldn't help but have the urge to vomit but your body refused. You felt each fiber of the cursed gummy bear dissolve in your stomach acid and slowly start to shift your cells.

It took weeks to recover to your natural state of "feeling normal" but there was an overwhelming sensation of power. Your cursed energy spiked through the roof and you were now capable of being the most wanted cursed spirit.

That was years ago of course. You are now the most wanted cursed spirit and your intentions are unknown to sorcerers which is why your bounty said 'wanted alive' on it.

You found yourself encountering multiple high leveled sorcerers at a local fair of your home town, the couldn't recognize you at the time though. Gojo was among the crowd and watched the parade float pass while drinking a soda. His glasses had a bright shine to them from the lights in front of him which complemented the same shine against his white hair. He glanced in your direction a few times but didn't pay much attention to specifically you.
