mamaguro died and toji loved her sm, and he couldn't shoulder the weight of his own curses without her. it's not that toji dgaf about megumi, but he couldn't love him enough to win against his own demons without mamaguro, while megumi just thought he'd never cared.

megumi is just an innocent victim in all this. megumi, who was born out of so much love and hope, who will never get to know it, bc there's no one around who even knows anymore. they can heal his other traumas, but never the earliest ones, to let him know that he's always been loved from the start
