Okay, I kinda love this one. I'm proud of this. Enjoy!
Kei woke up with a pulsing headache.
God, what did I do last night?
He sat up, holding his head. His other hand was feeling around for his glasses. When he found them, he discovered that he was in his bedroom, and had no clue how he'd gotten there.
He groaned and ran a hand through his hair, noticing the empty bed beside him.
Where's Y/N? And what happened?
You'd been dating for just over six years, and Kei planned on proposing soon. He had the ring in his desk drawer, but now he had no clue what was going on.
The bathroom door opened, revealing a woman that was definitely NOT you. She was also only wearing a thin nightgown.
"Hey darling," she said with a smile. "You wanna have another round, or get some breakfast first?"
He tensed.
"Who are you?" he asked sharply.
Please don't tell me...
"Oh, does that matter now?" She asked sweetly. "You didn't seem to care last night, but whatever. I'm Aiko."
Kei's hand gripped the bed sheets, and he noticed he was only wearing his underwear and a pair of shorts.
"Why are you in my house?" He asks.
Aiko laughs airily.
"You must've been really drunk last night. Don't worry baby, I'll clear out before your side hoe gets back."
He freezes, and the girl raises an eyebrow.
"You don't still want her do you? We had such a fun time last night, I can barely walk. You said I was better at it anyways."
Kei's hands started shaking as her words sank in.
No, no no I didn't. She's wrong.
But he couldn't remember anything after Kuroo handed him his drink last night. Him and Y/N had gone out to a high school reunion party, and he hadn't meant to get drunk.
He shook his head, regretting it when the headache intensified.
"Out."
Aiko frowns.
"Baby, don't be-"
"Don't call me that. Whatever happened last night was nothing. I need to find my girlfriend."
Kei stood up, quickly slipping a shirt over his head. Aiko was still looking at him.
"Oh come on," she said. "Darling, you can't be serious."
He turned and glared at her.
"I'm dead serious, get out of my house."
Aiko pouted and left, while Kei changed into a shirt and pair of khakis and left the apartment. He needed to tell you what happened. Even if you hated him. It was only fair that you know.
He got into his car and drove the five minutes to your work, because it would be just a little faster.
The small coffee shop wasn't busy, and he walked in, frantically looking for you. When he saw you he walked over and grabbed your hand.
"Kei? What are you doing here?" You ask, surprised to see him look so nervous.
"We need to talk," he said. "Right now, it's important."
