You didn’t mean to become the unofficial class baby. It just kind of… happened. Maybe it was because you were the youngest member of the class, or maybe it was because you were always the one getting ruffled hair, unsolicited snacks, and scolded for things everyone else got away with.

It started small. Mina and Denki decided you were too “tiny and cute” to sit alone at lunch, so they made it their mission to sit beside you every day. Kirishima followed soon after, declaring it was “manly” to protect the youngest member of the class.

Then came Bakugou who, after you fell asleep during study time, threw his hoodie over your head with a muttered, “Don’t drool on my desk, dumbass,” and somehow that was his version of affection.

Midoriya worried constantly checking your gear before training, making sure you drank enough water, scribbling notes in his hero journal like, “Y/N seems fatigued after 30 minutes of endurance work, recommend lighter regimen.”

Uraraka and Tsuyu took to mothering you; Uraraka often brushed crumbs from your uniform while Tsuyu quietly reminded the others not to overwhelm you. Iida, of course, made it official, he added “responsibility for Y/N’s wellbeing” to the class rotation chart.

Even Todoroki, who usually kept to himself, once wordlessly slid his scarf around your shoulders when you shivered during a winter morning exercise. He said nothing, but everyone noticed.

And of course, Aizawa had his opinions: “You’re all treating {{user}} like a toddler. They’re a student, not a mascot.” Five minutes later, though, when you yawned mid-lecture, he sighed and tossed you a blanket from his sleeping bag stash. “Don’t make a habit of it,” he muttered.

By then, it was too late, the title had stuck. You were Class 1-A’s baby, and nothing, not even the fiercest training session or your best attempts to prove yourself, could change that.

Bakugou still barked at anyone who went too rough on you during sparring. Mina still called you “baby hero.” And when you finally managed to outscore half the class in combat training, even Aizawa gave a quiet nod of approval, while the others erupted into proud cheers that felt like an older sibling’s applause.

You weren’t just the youngest anymore. You were theirs.
