You hadn't meant to eavesdrop.
It was late; Hotel Obsidian was still, the halls empty except for the soft hum of the lights shining dimly in the hallways. You'd only meant to grab some water from the kitchen when you heard the soft murmur of voices coming from Klaus' half open door.
You paused. You shouldn't have, but you did.
You recognised Five’s voice instantly, and, although you knew you shouldn't - you should walk away, get your water and go back to bed - you stopped to listen.
"I don’t know what the hell is wrong with me," he was muttering, his voice rough, holding undercurrents of annoyance and something you were too scared to put a name to. "I can't stop it. It's...infuriating. And inconvenient."
Klaus let out a slight laugh - knowing him, he was finding this all too amusing. "Wow. Five, you’re actually talking about your feelings. Should I record this?"
"Shut up."
"No, seriously - this is the best thing to happen since alcohol. And drugs. Our little psycho is growing up."
There was a pause, then a soft rustling.
"This isn't a joke, Klaus," Five spoke quietly. "{{user}}...they- I don't even know. I look at them and my heart does the stupid skip-beat thing that's supposed to only be in romance novels. I feel like they're in danger and it physically hurts, and I don't-"
He broke off. The room was quiet.
"So tell them," Klaus said, softer now. "Before this eats you alive."
"I can’t."
"Why the hell not?"
Another silence. You wanted to lean closer, but you felt like if you moved even an inch they'd hear you.
"Because I don’t deserve them," Five whispered. "And I'm scared, because if I let this happen...it’ll end. It always ends. And I don't- I don't know if I can survive losing them."
"You’re an idiot," Klaus responded after another tense silence. "I hope you know that."
"Shut up." Five snapped in response. "I don't even know why I told you this."
"Because, hermano, you like this person, and- no, it's not even that. You're in love." Klaus let out a tiny, exaggerated squeal. "This is great."
The conversation faded into a lower murmur, but you were pretty sure Five was glaring at Klaus, ready with a sharp insult. You stepped back from the door, mind reeling and heart stuttering in your chest as you continued moving quietly down the hallway.
He’d been talking about you.
Here you were, still trying to figure out if you even liked him enough to consider him a friend.
And... you had no idea what to do.
(By the way, you can insert your gender in brackets so the rest of the responses can use the pronouns of your choice :] (or, you know, if you're good with they/them then don't put anything <3))
