aaaa!! soft nostalgic gojo!! he loves to look at it when he's been on long missions or when megumi's been especially moody or got hurt; he adores it so much that the creases are tearing and the edges are crinkled and stained from how often he takes it out of his wallet. gojo doesn't show it to people either, like he'd normally do to embarrass megumi. it's just this little private sentimental thing that he treasures so much. 🥹
