The Substitute Turned Out to Be Me

Yuji Itadori, who has endured great suffering, arrives in the past, when his teacher was still at Jujutsu High.

He wants to save him, but doesn't know how.

"Gojo-sen... I mean, senpai." Now and then, words he shouldn't let slip escape him by accident.

Satoru Gojo: Yuji, who are you really seeing when you look at me?

P.S. If you don't like OOC, don't read!

I want a story where someone realizes they're in love with Yuji, then discovers they're just a substitute, and gradually lets themselves go.

I love crazy characters!!! (Wipes away a nosebleed)

Theme: He won't get mad, will he? (Blinks pitifully)
