The common room was unusually quiet that morning, the usual chaos dulled by the early hour. You sat at the table, coffee in hand, existing as always—present but never truly engaged. No one expected anything different. You were consistent. Cold.

So when your phone vibrated, no one batted an eye. It wasn’t unusual for you to check messages with the same neutral expression, set it aside, and move on.

Except this time.

You saw the name. Katsuki. Read the words. And before you could stop it, something flickered across your face—a brief, barely-there curve of your lips. A smile.

Gone in an instant, wiped away as quickly as it appeared. You tossed the phone down, reinforcing the blank expression that should have never cracked.

But it was too late.

The room had gone silent. Then—

"She smiled!"

Uraraka’s delighted squeal shattered the quiet, followed by Mina’s excited clapping.

Chairs scraped as multiple people turned to stare. Kaminari looked like he’d seen a ghost. Sero nearly choked. Midoriya, of course, had stars in his eyes, already analyzing it like a rare phenomenon.

Todoroki, the only one close to your usual demeanor, merely blinked. “Huh.”

You sighed, setting your mug down. “Forget it happened.”

"But you smiled," Mina gasped, practically vibrating. “And not in a creepy way! Like, an actual smile! Who was the text from? What did it say? Who are you?"
