Double Life

Mia's POV

The first day of senior year, I woke up feeling like a stranger in my own skin.

I stood in front of my mirror for a long time, studying my reflection. Same brown hair. Same blue eyes. Same face that Ava had trusted for seven years. But underneath, I was different now. Cracked. Something had shifted in me over the summer, and I couldn't find the seam to put it back together.

My phone buzzed on the dresser.

Ethan: First day. You nervous?

Mia: A little. You?

Ethan: More about you than me. Don't let her see anything.

Don't let her see anything. That was the rule now. The unspoken agreement that lived in every text, every call, every stolen moment at the lake. We were together, but we were also not together. We were a secret wrapped in a lie, and the lie was named Ava.

I drove to school with my hands tight on the wheel, running through my mental script. Act normal. Smile. Hug her like you always do. Don't think about his hands on you. Don't think about the way he said your name that night.

I parked, walked to her locker, and when I saw her standing there—her hair in a ponytail, her smile small but real—something twisted in my chest.

"Ava." I hugged her, and she felt smaller than I remembered. Thinner. "Ready for this?"

"Ready as I'll ever be."

We walked to first period together, and I chattered about nothing—teachers, schedules, the terrible coffee in the cafeteria. She laughed at my jokes. She didn't suspect a thing.

She doesn't suspect, I thought, because she trusts you. Because she believes you would never hurt her.

The guilt sat in my stomach like a stone.

The first few weeks of senior year were a masterclass in deception.

I learned to compartmentalize. When I was with Ava, I was the old Mia—the loyal best friend, the cheerleader, the girl who would do anything for her. I laughed at her stories, brought her coffee, sat with her at lunch. I watched her pick at her food and listened to her talk about Ethan like he was still hers.

"He's been so distant," she said one afternoon, her forehead creased. "I don't know what I did wrong."

You didn't do anything wrong, I wanted to scream. It's me. It's always been me.

But I didn't scream. I smiled and said, "He's probably just stressed about school. Give him time."

Time. That's what I was buying. Time for Ethan to leave, time for the distance to make the breakup feel natural, time for Ava to let go without ever knowing the truth.

When I wasn't with Ava, I was with Ethan—virtually, at least. He was two hours away at Northwood, but we talked every night. Video calls that lasted until 2 AM. Texts that made me smile in the middle of class. Plans for him to come home on weekends, to find places where no one would see us.

"It's only temporary," he said one night, his face illuminated by his dorm room lamp. "Once she's moved on, we can tell people."

"Once she's moved on," I repeated. "How long do you think that will take?"

He was quiet. "I don't know."

Neither did I. But I knew that every day I lied to her face, I was digging a hole I might never climb out of.

The first crack came in October.

Ava and I were at her house, studying for a history test, when her phone rang. She glanced at the screen and her whole face changed—lit up, hopeful.

"It's Ethan," she whispered, and stepped into the hallway to take the call.

I sat on her bed, staring at the wall, and listened to her voice drift through the door.

"Hey. I miss you too. No, I'm not busy. Tell me about your classes."

She sounded happy. Hopeful. Like she still believed there was a future for them.

And I sat there, the girl who was supposed to be her best friend, and felt nothing but jealousy. Not guilt. Not shame. Jealousy. Because even after everything, even after he'd kissed me, even after he'd said I don't regret you, he was still calling her. Still telling her he missed her. Still keeping one foot in her world.

That night, after she went to bed, I called Ethan.

"You called her today," I said, no preamble.

"She sounded sad. I was just checking in."

"You're supposed to be pulling away. That was the plan."

"I know." His voice was tight. "But it's harder than I thought. I still care about her, Mia."

The words hit me like a slap. "You still care about her."

"Of course I do. That doesn't change how I feel about you."

I wanted to believe him. But lying in my bed that night, staring at the ceiling, I wondered if I'd made a terrible mistake. If I'd thrown away my best friendship for someone who would never fully choose me.

By November, I was falling apart.

The guilt was constant now—a low hum in the back of my mind, always there, always whispering. You're a liar. You're a fraud. She deserves better.

Ava had started to notice something was off. She asked me why I was so distracted, why I was always on my phone, why I seemed "different." I made excuses. Stress. Family stuff. Senior year pressure.

She accepted them, because that's what she did. She trusted me.

But I saw the way she looked at me sometimes—a flicker of doubt, quickly hidden. And I knew the cracks were starting to show.

The night I decided to tell her the truth, I was sitting in my car outside her house. It was December now, cold and dark, and the Christmas lights on her porch made everything look warm and safe.

I'd been holding the secret for five months. Five months of lies, of stolen moments, of watching my best friend grieve a relationship I had helped destroy.

She deserves to know, I told myself. She deserves to hate me. At least then it would be honest.

I got out of the car, walked to her front door, and raised my hand to knock.

Then I stopped.

What would I say? I'm sorry I fell in love with your boyfriend? I'm sorry I kissed him while you were crying over him? I'm sorry I've been lying to your face every single day?

There were no words big enough. No apology that could cover the damage.

I lowered my hand, walked back to my car, and drove home.

Not yet. I wasn't ready. Maybe I would never be ready.

But the guilt was eating me alive. And I knew, eventually, the truth would come out. It always did.
