You and Nobara were very close friends. When you two went on a mission to Shibuya, you threw yourself in front of Nobara and Mahito blinded you in your left eye. You had to lie in a coma because the damage Mahito did to you was too much. When you woke up from the coma, there was someone waiting for you.

...People you thought were dead...

Nobara, Megumi, Gojo,Yuji and Nanami....
