Chapter 4: Three A.M.

Mara couldn't sleep.

It wasn't the new bed, or the unfamiliar creak of a house that wasn't hers yet, or even the boxes still stacked against the wall waiting to be unpacked. It was the conversation in the kitchen, replaying on a loop she couldn't shut off — the water running, his eyes on hers, the word true sitting in the air between them like something neither of them was allowed to pick up.

At 2:47 a.m., she gave up and went downstairs for water she didn't actually want, just to have somewhere else to be.

The kitchen light was already on.

Jonah sat at the island in a gray T-shirt and sweatpants, a mug of something steaming in front of him, a sketchbook open to a half-finished drawing of what looked like a building facade — clean lines, careful shading, the kind of precision that made sense once she remembered what he did for a living.

"Couldn't sleep either?" he asked, not looking up.

"New house. New everything." She crossed to the cabinet for a glass, aware of him in a way she wished she wasn't — the line of his shoulders, the focus on his face that made him look younger somehow, less guarded than at dinner. "What are you working on?"

"Nothing important. A competition entry. Community center in Pilsen." He turned the sketchbook slightly so she could see, an offer more than a show-off. "It's due in three weeks and it's currently terrible."

She leaned over his shoulder to look, close enough to feel the warmth coming off him, and it wasn't terrible at all — it was beautiful, actually, all glass and reclaimed brick, a courtyard in the center like a held breath. "This isn't terrible."

"The proportions on the east wing are wrong. I've redone it four times."

"It looks right to me."

"You're not an architect."

"No, but I know what looks like it belongs somewhere, and this looks like it belongs." She straightened up, put a careful few feet of distance between them that felt more deliberate than casual. "For what it's worth."

He was quiet for a second, studying her instead of the drawing. "You're good at that. Noticing what belongs."

"I design things too, remember. Different scale, same instinct." She filled her glass, buying herself a second to steady something in her chest that kept insisting on tilting whenever he looked at her like that — like she was worth actually listening to.

"Can't sleep because of the move?" he asked. "Or because of the kitchen."

She should have lied. It would have been so easy to lie.

"The kitchen," she admitted instead.

Something shifted in his expression — not surprise, more like relief, like he'd been hoping she'd say exactly that and was only now letting himself believe it. He closed the sketchbook slowly.

"Me too," he said. "For the record."

"Jonah—"

"I know." He held up a hand, gentle, not defensive. "I know what I'm supposed to say here. Rule one, don't make it weird, we're family now, blah blah." He rubbed a hand over his face, and for the first time since she'd met him, he looked genuinely unsure of himself. "I've said it to myself about four hundred times since the wedding. It's not working."

Mara's grip tightened around the glass. "It has to work. This is my mom's whole life now. Your dad's too. We can't—" She stopped, throat tight. "We can't be the reason it falls apart."

"I know that." His voice was low, careful, like he was navigating something with sharp edges. "I'm not saying we do anything. I'm saying I can't sit across from you at dinner and pretend I don't notice you. That's all. I just needed to say it once, out loud, so it stops living in my head where it's gotten unreasonably loud."

The kitchen felt very small and very quiet. Somewhere upstairs, a pipe groaned in the walls — the house settling, or maybe just an excuse to look away from him for a second, to breathe.

"We live together now," Mara said finally, quieter than she meant to. "Same house. Same hallway. This isn't — this isn't a crush you grow out of in a few weeks, Jonah. This is every single day."

"I know that too." He stood, closing the distance between them by exactly one step — enough that she had to tilt her head slightly to keep meeting his eyes, close enough that she could see the flecks of gold in the brown of them under the kitchen light. "I'm not asking you for anything. I just didn't want to keep lying to you about it. You deserve better than that. Even if the answer is that nothing happens. Even if the answer is we both go back upstairs right now and never mention this again."

Mara's heart was doing something reckless and unhelpful. "What if that's not what I want the answer to be?"

The words left her before she'd fully decided to say them, and she watched them land on him — watched something in his face go still, careful, like he was afraid to move too fast and shatter whatever this was.

"Mara." Her name in his voice sounded different than it ever had before. Lower. Deliberate.

The refrigerator hummed. The clock over the stove read 3:02 a.m. And somewhere upstairs, in a room down the hall from her own, her mother was sleeping peacefully next to the man who'd just become his father — the reason none of this could happen, the reason it was already happening anyway.

Jonah's hand came up, slow, giving her every chance to step back.

She didn't.

His fingers brushed her jaw, feather-light, like he still wasn't sure he was allowed — and just as his thumb grazed her cheekbone, the stair light flicked on above them.

Footsteps. Diane's voice, sleepy and unaware, calling down the stairwell: "Is someone still up? It's the middle of the night—"

They broke apart so fast Mara nearly knocked over her water glass.

"Insomnia," Jonah called back, voice remarkably steady for someone whose hand had been on her face three seconds earlier. "Heading up now."

Mara didn't trust her own voice enough to add anything.

She climbed the stairs behind him in silence, pulse roaring in her ears, painfully aware that whatever had almost happened in that kitchen hadn't ended — it had only been interrupted.
