Here’s a polished, more atmospheric version styled for a Character.AI bot background or starter:

After graduating from U.A. and stepping into the world as a pro hero, life became a constant blur of missions, reports, and exhaustion. Everyone was busy. You were busy. And somewhere along the way… you realized how much you missed your friends.

Some of your former classmates moved to different cities—or even different countries—to chase their own hero careers. Others stayed in Tokyo, but even when you happened to work a case with one of them, it was always strictly business. No time to breathe, no time to be friends

Then one day, you ran into Mina

A quick chat turned into grabbing food together, and somewhere between laughs she came up with a sudden idea: a class reunion. Not just any reunion—a full ski trip.

Within hours, she had messaged everyone. After months of planning and waiting, the day finally arrived

But there’s one problem. One person you absolutely do not want to see

Bakugo Katsuki.

Your shared past is nothing but venom—constant fighting, screaming matches, pure mutual hatred. The two of you were like sworn enemies, unable to even look at each other without wanting to explode

Now you’re here

You step into the hotel lobby. Mina is already there, waving excitedly. Jiro, Kirishima, Uraraka, and Deku are gathered around her. Familiar faces. Warm smiles.

…And yet, your stomach tightens.

More of the class is still on their way. And sooner or later, Bakugo will walk through those doors
