The snow continued to fall for three more days, thick and silent, burying the city in white. Every morning, Luffy awoke with the same dull pressure in his chest, a pressure that came and went like a friend he knew too well. He tried to tell himself it was the cold, the late nights at the café, the worry he couldn't shake about the man in the long coat. He tried to tell Catherine the same when she asked him why he absently rubbed his chest while they drank their morning coffee together.
"Just heartburn from too many chestnuts," Luffy said with a crooked grin.
She didn't laugh. She looked at him too closely now. She saw when his breath hitched on the stairs, when he paused in midsentence and pressed a hand over his chest.
But on that Sunday, the sky was clear at last. The pale winter sun broke through, making the snowblind. Catherine said they should go out.
"We've been cooped up too long. Fresh air. Walk to the park. The cats can stay home this time. Shadow has been staring out the window like he's on guard duty, anyway."
Luffy paused for a moment. "Yeah. Let's do it."
Catherine was bundled up in Luffy's stolen black hoodie. Luffy wore the charcoal scarf she'd knitted last winter. Their hands were linked together before they even left the house.
The streets were silent. Snow fell, covering all sound. Their feet crunched out a beat on the snowy road. Their breaths made small clouds of white between them. Catherine swung their linked hands back and forth.
"Remember our first beach walk?" she said. "You brought a thermos of coffee, and we got salt in our hair."
Luffy's voice was soft. "I remember you laughing so hard you snorted when I tried to draw a heart on the sand, but a wave came and swept it away before I finished."
"I still have that shell from that day. The one that looks like a tiny, broken heart."
He squeezed her fingers again. "Broken things can still be beautiful."
They walked to the park, the benches covered in a thick layer of dust, children playing with snowballs in the distance. Luffy walked her to their favorite spot, the low wall near the frozen pond, where they had sat feeding the ducks before the cats entered their lives.
They sat close, their thighs pressed together for warmth, Catherine leaning her head against his shoulder.
"Hubby?"
"Hmm?"
"If something was wrong, really wrong, you'd tell me, right? Not 'heartburn.' Not 'tired.'"
Luffy stared at the ice on the pond, watching as small cracks developed in the surface from the weak warmth of the sun.
He breathed deeply, wincing in pain, more than he should have.
"I've been feeling it for a while," he admitted, his voice low. "The ache. It comes and goes, worse when I'm stressed."
Catherine raised her head, turned to face him.
"How long is 'a while'?"
"Since… before Shadow showed up. Before the new apartment. It got quieter after we moved in. Like being with you made it smaller. But lately…" He rubbed his chest again. "Lately it's louder."
Instantly, tears appeared in Catherine's eyes.
"Why didn't you say anything?"
"Because I didn't want to scare you. Because we're finally happy, Catherine. Really happy. I didn't want to break that."
She cupped his face with both of her gloved hands.
"You don't get to decide what breaks us alone. We decided together. Every promise. Every paper ring. Every night we said 'forever.' If your heart is hurting, then my heart is hurting. That's how this works."
Luffy closed his eyes, leaned into her touch.
"I'm scared," he said. "I'm so scared it's the same thing that killed my dad. He was forty-two. Just… dropped one morning making breakfast. I was nineteen. I still hear the pan hit the floor sometimes."
Tears streamed down Catherine's face, freezing on her cheeks.
"Then we go to the doctor. Tomorrow. First thing. No waiting. No excuses."
He nodded, swallowing thickly.
"Okay."
She hugged him tightly, arms wrapping around his shoulders, her face buried in his scarf.
"We're going to fix this," she said, her voice muffled against his scarf. "Or manage it. Or fight it. Whatever it takes. But you don't carry it alone. Not anymore."
Luffy hugged her back, his arms wrapping tightly around her, his nose buried in her hair, smelling vanilla shampoo, cold air, love.
"I love you," he said, his voice rough with emotion. "More than coffee. More than cinnamon rolls. More than every cat we'll ever adopt."
She sniffled, laughing through her tears. "High praise."
"Highest," he said, his voice a little stronger now.
They sat like that for a while, until their fingers went numb, until the sun began to dip lower in the sky.
On the walk home, Catherine never let go of his hand.
When he went inside the apartment, Shadow was there to greet him at the door, tail held high, eyes fixed intently on Luffy's face as though he already knew.
"Meow," he rubbed harder than usual against Luffy's legs, purring so low it was almost a rumble.
Catherine knelt down beside Shadow, scratching behind his ears.
"You knew, didn't you?" she said softly to the cat. "That's why you went when you did."
And Shadow nudged his head against hers twice, then turned and went into the bedroom, leaping up onto the bed and going to the exact center of it, leaving space on either side of him.
Luffy watched him, a softening look on his face.
"Maybe he did," he said softly.
That night, they called the cardiologist to schedule an appointment for first thing the next morning, at nine a.m. sharp. Catherine called to cancel all client meetings for the next week. Luffy closed the café for a "family emergency," one Rohan understood without prying.
They lay in bed, lights off, only the streetlamps illuminating the night.
Catherine drew circles over Luffy's heart with the tip of her finger.
"No matter what the doctor says tomorrow," she said softly, "we're still us. Still Hubby and Wifey. Still paper rings and too many cats and late-night mango ice cream. Nothing changes that."
Luffy's hand closed over hers, pressing it flat against the steady, though slightly irregular, rhythm of the heartbeat under his ribs.
"Nothing changes that," he repeated.
Shadow crept closer, nestling into the crook of Luffy's side, his paw falling exactly over Catherine's hand.
Three heartbeats: one human, one fragile, one unswervingly loyal.
Outside, the snowfall had ceased.
Inside, the pain had a name.
And the struggle: the real one: was only just starting.
