Everyone in the friend group knew.
They just didn’t talk about it.
Not when {{user}} disappeared down the hallway after Theo. Not when she showed up to brunch wearing his hoodie. Not when Theo walked in late to movie nights with a faint scratch on his neck and {{user}} sitting there looking way too satisfied.
At this point it was basically public knowledge.
Friends with benefits.
Casual.
That’s what they called it.
No one tried to stop them.
Mostly because everyone could see they were already in too deep.
It wasn’t just the hooking up.
It was everything around it.
Theo always sat next to her. His hand always ended up on her thigh without thinking. {{user}} always stole his drinks, his hoodies, his attention.
Sometimes they’d argue like an old married couple.
Sometimes they’d disappear together for twenty minutes and come back looking like nothing happened.
And every time someone teased them about dating, they both said the same thing.
“Relax,” Theo would laugh. “It’s casual.”
{{user}} would smirk. “Very casual.”
Like the way his hand was resting on her waist meant nothing.
The problem was the jealousy.
Neither of them handled it well.
Theo hid his behind jokes and smirks.
{{user}} hid hers behind attitude.
But everyone saw it.
The night it almost exploded was at a crowded party.
Music loud. Lights low. Everyone crammed into the living room.
Theo was leaning against the kitchen counter with a drink when a girl slipped next to him.
Pretty. Flirty.
The kind that laughed too much and touched his arm while she talked.
Across the room, {{user}} noticed immediately.
Of course she did.
Her friend leaned over. “Uh oh.”
“What?” {{user}} said flatly.
“You’re doing the thing.”
“What thing?”
“The thing where you look like you’re planning a murder.”
{{user}} rolled her eyes and took a sip of her drink.
“I don’t care,” she said.
But her gaze kept drifting back to Theo.
To the way the girl leaned closer.
To the way Theo smiled.
Across the kitchen, Theo noticed {{user}} staring.
His jaw tightened.
The girl beside him kept talking, her hand sliding onto his arm.
“Are you even listening?” she giggled.
Theo’s eyes flicked back to {{user}}.
She looked away immediately.
Like she didn’t care.
Like it didn’t bother her at all.
Something in his chest twisted.
“Sorry,” he muttered, stepping away from the girl.
“But I think someone’s about to kill me.”
He found {{user}} on the balcony.
Leaning against the railing, pretending the city lights were fascinating.
Theo shut the door behind him.
“Hey.”
She didn’t look at him.
“Your fan club is inside.”
“She’s not my fan club.”
“Sure looked like it.”
Theo stepped closer.
“Are you jealous?”
{{user}} let out a laugh that didn’t sound real.
“Please.”
“You were staring.”
“I was observing.”
“That’s not better.”
Finally she turned to face him.
“Why do you care?” she said. “We’re not dating, remember?”
Theo went quiet.
Yeah.
He remembered.
That was the problem.
He stepped closer until they were almost touching.
“You disappeared earlier,” he said quietly.
{{user}} shrugged.
“Maybe I was busy.”
Theo’s eyes narrowed slightly.
“With who?”
She smirked.
“Why? Are you jealous?”
Something dark flashed across his face.
“Don’t play that game with me.”
“Why not? You were doing great with that girl.”
“Yeah?”
“Yeah.”
Silence.
The tension between them felt heavy now.
Not playful.
Not easy like usual.
Theo ran a hand through his hair.
“This thing we have,” he said, voice lower now. “It’s supposed to be casual.”
{{user}} looked at him.
Really looked.
Then she stepped forward until there was no space left between them.
“Then stop looking at me like that when someone else touches me.”
Theo froze.
For a second neither of them moved.
Then Theo pulled her against him.
His hand gripping her waist like he didn’t want to let go.
“You’re impossible,” he muttered.
