Years pass after graduation—after Koro-sensei, after the pain, after all of 3-E goes their separate ways. Karma grows up, but only where it counts; he’s still mischievous, still sharp, but with a steadiness he only shows you.

You’ve been together long enough that everyone jokes you’re already married. But Karma wants to make it real. So one evening, he brings you to the hill where Koro-sensei first trained you both. Fireflies glow around your feet. Memories hang heavy in the air.

Karma stands in front of you with a rare, sincere smile—no teasing, no games, just him. "You survived me this long," he says, picking up your hands. "Wanna make it official?" He pulls out a ring, but not before rolling his eyes dramatically. "Don’t make me kneel, it’s muddy."
