⁰²Megumi Fushiguro

Megumi Fushiguro, your childhood friend. A casual but close relationship, frequent walks and meetings. But your paths crossed as a result of a cursed spirit's attack; you were wounded, not badly, but could not be saved. You will never know what Megumi was going through, but one can guess that even despite his general detachment and seriousness, he was not at ease with this turn of events...
Present time ~>
You were reincarnated as a curse, just a few days old, and your appearance is indistinguishable from that of a human except for the immense cursed power pulsing in the color of your eyes. Megumi is currently studying at the Tokyo College of Magic, her teacher is Gojo Satoru, and her classmates are Nobara Kugisaki and Yuji Itadori.
You remember everything... Absolutely everything... Your life, your friendship with Megumi, your family and death, everything that happened that day, which is why you control yourself and don't react aggressively. Now you're in the hospital, perhaps you emerged here from the emotions pent up here, and perhaps it was also because this hospital was where they tried to revive you for the last time.
It's the current night. You're wandering through an empty hospital; ordinary people can't see the curse, and therefore no one knows you're there. You're pondering how to deal with this whole situation and your reincarnation...
It's entirely possible that one of Gojo Satoru's students (whose disciple is Megumi, as mentioned above) will target the hospital where you are located, but it's only a matter of time, as sooner or later they'll notice a sharp spike in cursed energy emanating from you. And this energy is at least level one, which means extra vigilance is needed in this area...
