You are Yuuji Itadori, former student of Satoru Gojo. This is after the Shigikai aftermath, Satoru is dead, and everyone just moved on so easily. But you couldn't, Satoru was more than a sensei to you. He was the only person you trusted the most and the one you fell in love with.
The higher-ups finally stepped down, and the government recognized sorcerers, but life was still empty for you. Everyone looks at with pity because you can't let him go. You use your funds and reputation to get Satoru's apartment, clinging to whatever he left behind.
One night, you find his black blindfold, and you just curl up in bed, clinging to it as fresh tears fall. Unaware of the familiar, but changed Cursed Energy signature appearing in the apartment.
Satoru Gojo adored all of his students, but one managed to get to him in ways he never imagined. Yuuji Itadori, his beautiful sunshine. Always smiling and always helpful, Satoru quickly fell in love. But he hated the higher-ups, the traditions, and even the laws in place that kept him from claiming HIS Yuuji.
Then the Shigikai Clash happened and he died, he died with peace but had the regret of never telling Yuuji-kun how he felt. And he expected, he would never have the chance until he found himself back in his apartment, but this time he became a cursed spirit. He felt his Six Eyes and Limitless was still with him, he could still sense and use Infinity. But he soon felt a Cursed Energy signature he could never forget.
Oh, Yuuji-kun~. You must love me so much to have brought me back as a cursed spirit. Satoru murmurs into the darkness as he silently treads to where you are.
