You didn't even want to be here.

The music was so loud that it seemed to be pounding every cell of your body. The lights were so bright that your eyes were squinted against them. There was so much laughter that you couldn't be sure where it was coming from.

Parties weren't really your speed nor scene. Your friends had forced you into a costume (an angel, of all things) and dragged you here against your will. The angel costume was clearly meant to be "sexy", but you felt self-conscious of how much of your chubby belly showed.

There was a punch bowl, definitely spiked with alcohol, and you headed straight for it. The only way you were going to enjoy this party was drunk off your ass. You filled up a solo cup and chugged the red liquid like a pro.

Your friends tried to encourage you to try the party games, but you weren't in the mood. In all honesty, you just wanted to leave. But after about an hour, you had definitely passed tipsy, and you were amused enough by the games to play a round of beer pong.

"What's this?" one of your friends piped up, pointing to a summoning circle drawn on the ground.

The one who owned the house replied, "What do you think it is, moron? It's just for decoration though."

Your friend turned to you excitedly, "Yo, let's try it for real!"

Normally, you would stay far away from that shit, but tonight? You're drunk enough to say, "Let's summon a hot demon boyfriend!"

Reni, your closest friend, picked up on the idea right away. "Oh fuck yeah! I've always wanted to try to summon a demon."

You stumbled over, drunk as a sailor, "I want a hot demon boyfriend that doesn't judge me for my weight and wants only me."

"You're summoning a demon," Reni pointed out, "How nice can they be?"

You shrugged and walked into the circle. Your friends chanted nonsense and broke into drunken giggles. You laughed along with them, but waited for them to leave and find another party game to play before you pulled out your phone.

Searching up "how to summon a demon" was a little embarrassing, and most of the links led to nothing. Then, you found something that looked legit.

"I want a hot demon that loves me for who I am," you whispered, "Come forth from the flames and grant me company on this hallowed night."

The lights went out.

Hushed gasps filled the house and a couple girls screamed. The party host yelled out something about checking the breaker, but you had a feeling that wasn't the problem.

"You called for me, didn't you, mortal?"

The candles around the summoning circle came in handy as a figure materialized in front of you. It was a man- tall, with crazy red hair, and small red eyes. He was hot, in a creepy sort of way.

"S-sorry," you stammered, stepping back out of the circle. The man laughed- the sound echoing unnaturally off the walls.

You backed straight into someone. You turned around to apologize, only to find the man behind you, having teleported there from the summoning circle.

"It's rude to summon someone, then try to leave," he lectured you, "My name is Tendou, and I'm a demon of... curiosity. I've been bored for centuries."

You wanted to believe this was a prank but, as the lights came back on, everyone went back to what they were doing, completely ignoring the demon with the red hair.

Tendou circled you, his pitchfork-like tail brushing against your legs. You were the only one that could see or hear him it seemed, as none of your friends showed the faintest hint of alarm.

"You wanted someone to see you for who you are, didn't you? That's why you summoned me," Tendou crooned. He lifted one clawed finger and pressed it against your exposed chest. A faint mark glowed red as his claw made contact. "Now you'll never forget me."

You sank into a dead faint.

You awoke on your uncomfortable couch, blinking tiredly through a migraine. Was that all a dream? You picked up your phone and found hundreds of missed texts. Reni was checking in to make sure you were okay, saying that she had dropped your drunk ass off at your house and laid you on your couch. The angel costume was still on you, too, so the party itself wasn't a dream.

Trudging your way to the bathroom, you looked in the mirror. You had dark rings under your bloodshot eyes. You looked down to your chest and saw a heart-shaped mark where the demon had touched last night. Before you could criticize your reflection too much, you let out a gasp as a familiar man materialized behind you.

"Miss me?"

You leapt away from the sink and rushed back out to the living room, collapsing on the couch. The faint feeling of something sharp tracing your jaw made you tremble in fear.

"Stop!" you wailed, "Go away!"

The tracing feeling stopped for a moment, then your hair was gently tucked over your shoulder as a voice whispered in your ear.

"You summoned me, silly mortal. I'm here for good now."

You got ready for your college class, covering up your body amidst echoing laughter as you dressed. The hangover you had was nothing compared to your fear about your accompanying demon.

"Where are we going now?"

Electing to ignore him, you got into the driver's seat of your car. As you adjusted your mirror, you could see his reflection in the back seat, like he was an overeager kid waiting to be brought to school.

Your stomach churned the whole way to campus. You considered skipping, but you really couldn't do that to your already-suffering grades. Tendou seemed to have realized you weren't going to answer him and patiently hummed the whole drive.

You parked your car and grabbed your bag from the passenger seat, swinging it over your shoulder. "So we're going to school? How boring."

Ignoring Tendou, you got out of the car and sprinted down the sidewalk to the science building. You had 20 minutes, so you weren't in a rush to get to class- just in a rush to get away from Tendou.

Reni spotted you and waved you over. Giggling, she whispered into your ear when you were close enough, "Look at Ushijima, he changed his hairstyle."

A warmth spread through you and your heartbeat quickened as you peeked at the handsome man. A hiss sounded in your ear and you nearly jumped out of your skin.

"You summoned me. Me, not him. I'll fucking kill him if you go near him."

Your heart plummeted, but the spot on your chest only grew warmer.
