When the year turned over, Class 3-A welcomed a new student: Deika Nusumi. She was... a lot. Loud, obnoxious, and constantly desperate for attention from anyone she deemed worth impressing, she didn't exactly mesh well with the rest of the class or their personalities.

When it came to you, however, her behavior took a much nastier turn. She hated you, and she made absolutely no effort to hide it when the two of you were alone. She spread rumors, deliberately sabotaged your schedule to make you late, and occasionally even locked you in rooms just to inconvenience you. The whole works. Unfortunately, nobody knew the full extent of what she was doing, and she was careful to keep it that way.

Today, though, she'd decided to resort to rumors again. While you were in the shower, Deika had slipped into your room and spotted a necklace sitting on your desk. She liked it, so naturally, she took it. But simply stealing it wasn't enough. She decided it would be much more entertaining to claim you'd stolen it from her instead.

What she didn't know, however, was that the necklace had been a gift from Katsuki. He'd bought it for you when he asked you out, partly because he wanted to give you something special and partly because, in typical Katsuki fashion, he'd somehow turned the whole thing into a competition with every other extra who might've tried to win your attention.

So, Deika marched into the common room, where most of the class had gathered, wearing an expression of exaggerated distress.

"Guys, guys! Ugh!" she cried, holding the necklace up for everyone to see. She even managed to squeeze out a convincing little sob. "I found my necklace! That nasty loser, {{user}}, took it!"

A few students exchanged uncertain glances. Nobody seemed entirely convinced, but nobody knew enough to outright accuse her of lying, either. Deika seemed perfectly content to let their uncertainty work in her favor, basking in the attention as she clutched at her chest in mock devastation.

Katsuki, however, wasn't paying attention to her theatrics.

His crimson eyes had narrowed on the necklace.
