Caught between the people she loves and possibilities she's only beginning to discover, Mia has to ask: what does she actually want?

Dan texted again late that afternoon. “Heading out now. Be there in twenty?” I stared at the message until the screen went dark. Lillian had seen it too. After a long, loaded silence she just shrugged, and I typed back a reluctant “okay.”
He walked in like the apartment still belonged to him, casual and comfortable. He greeted Lillian with an easy smile and a “hey” that lingered a beat too long, then came straight to me. Before I could stiffen up he leaned in and kissed me, soft and familiar, his hand brushing my waist.
I let it happen for half a second, muscle memory, then pulled back sharply.
“Hey, fuck you, you can’t just do that,” I said.
Dan blinked, amused more than bothered. “Do what?”
“Kiss me like nothing happened. After last night. After you and Lillian—”
Lillian stayed on the couch, pretending to be absorbed in her phone, but I could feel her listening.
Dan sat his bag down on the kitchen table. “Lin told me you saw us.”
Oh, fuck her.
I peered at Lillian. She was staring fiercely at her phone, cheeks flushed, mouth shut.
“She told you?” My voice cracked.
Lillian finally spoke from the living room. “I told him the truth, Mia. Like we said. No lying.”
Et tu, Lin?
Jesus. Apparently my humiliation came with literary references.
I looked over at her. “We agreed on honesty between us.”
I waved both hands at Dan, because apparently he was now a whole category of problem.
“Not this.”
“Yeah.” He sounded so matter-of-fact. “She said you were watching. That you didn’t stop it. Sounded like you were pretty into it, actually.”
He smiled at me, the dense asshole.
My face went hot. Not cute-hot. Not sex-hot. Full stupid-caught-in-a-lie hot...
The rules Lillian and I had made that morning, our pathetic little grown-up pact, already felt meaningless. Adults. Strong women. Emotionally mature, probably.
Sure.
I felt fourteen again, fighting some stupid bathroom-stall war over a guy who had smiled at both of us.
“You think you can just use my best friend right outside my room and then kiss me?” I tried to keep my tone sharp, righteous. “She’s not some toy for you to...”
Lillian made a small sound from the couch, almost a laugh, in protest.
Dan stepped closer, backing me against the kitchen table. “She wasn’t complaining. And you didn’t exactly storm in and stop us.”
Lillian shifted on the couch but said nothing.
