WARNINGS: yandere themes

The sign proclaimed "Delta Phi Nu" in golden lettering, standing stark against the white marble arch. As soon as you walked under it, the door to the sorority flew open, girls streaming out to say hello to the newest addition.

It's a hailstorm of shrieks and glitter, overly-excited young women all surrounding you, all trying to talk to you at once. It was overwhelming, but it was also everything you had hoped for and more. Their enthusiasm was infectious.

Your suitcase rolled along the sidewalk, up to the steps to the sorority. You struggled to lift it up each step, the hot day causing sweat to materialize on your skin.

"You need help?" A voice called from across the street. It was a brown-haired guy in sunglasses, his brilliantly white smile blinding you more than the sun.

"No, I'm good," you called back.

Little gasps left the girls around you. One of them leaned forward and, in a conspiratorial whisper, said, "But that's Oikawa Tooru! President of Alpha Tau Omega!"

You looked back at her uncomprehendingly. "The most powerful frat on campus!" squealed another girl.

"Oh," you said simply, not sure whether to laugh or not. It was just carrying your suitcase up the stairs- it's not like you rejected his hand in marriage, like the women around you were acting like you did.

He gave you the creeps, and you weren't sure why. But it didn't matter all that much what you thought of him.

It's not like you'd be seeing him around much anyways.

—------------------------------------------------

"Oikawa Tooru. President, scholar, athlete and- if you're lucky- your future boyfriend."

You shook his hand and let out an awkward laugh. Typical frat boy.

Of course your sorority had paired with his frat for the Welcome Week Mixer, life just seemed to hate you that way. Everyone was in costume and, of course, Oikawa had somehow managed to complement your angel wings and halo with devil horns and a pitchfork.

"I guess this makes a match made in heaven," he grinned, gesturing from your costume to his.

You nodded politely and took your hand back. "Or hell," you muttered under your breath.

Oikawa either didn't hear you or didn't care. He leaned in and whispered, "Don't worry, angel, I protect you from all the demons tonight."

The courtyard was lit up with hundreds of fairy lights and music pulsed through the still night air. You moved closer to the bar, looking for an excuse to get away from the frat president. The menu was empty of usual picks and instead was filled with drinks named after the frat boys. "Oikawa's Elixir" seemed to be the flavor of the night.

Before you knew it, Oikawa was shoving a vodka cranberry with a pretty little red umbrella into your hands.

"How did you-?"

"I make an effort to know what my girl likes," Oikawa said smoothly.

"'My girl'?" you choked on your sip, giving him a look of utter suspicion.
