Jujutsu Kaisen: Sukuna Is an Actor

How should I put it... I'll keep it simple. I'm Sukuna, 32 years old, a kind-hearted middle-aged actor. After filming Jujutsu Kaisen, where I played a creepy old guy, I transmigrated. That's it. This all happened so suddenly... It all began on the final day, after the entire cast had wrapped filming... Normally, all I could say now is, “I hope everyone is okay.” But why does it seem like I'm the only one who transmigrated...?! Don't bully a kind-hearted old guy, okay? Otherwise, everyone will end up miserable! Reader advisory 1. OOC is inevitable. This is a silly story, so feel free to leave your brain behind. No outline, elementary-school-level writing, plot, character derailment, and villains getting away with everything. 2. I won't abandon it, but updates are whenever inspiration strikes. It's a silly old man story. 3. Well, first, please add it to your collection. Arigato! Unless something unexpected happens, it's a grandpa/grandpa pairing, featuring a quacking grandpa. Theme: Don't play someone else, or they'll end up miserable too.
