Five months after our divorce, I showed up at my ex-wife’s house on Christmas Eve convinced another man had replaced me—then she placed our six-day-old son in my arms.

By four in the morning, Leo began to fuss.

I panicked. In the boardroom, a hostile takeover merely required a sharp counter-strategy and aggressive leverage. Here, facing a seven-pound human turning bright red and squirming, my Harvard MBA was entirely useless.

"Shh, hey, Leo... it's okay, buddy," I whispered, swaying in circles.

I carefully checked his diaper, following the mental instructions from an article I hurriedly Googled on my phone with one thumb. Changing a diaper on a newborn turned out to be a high-stakes surgical operation. By the time I taped the fresh tabs down, sweat was beaded across my forehead, but Leo had stopped crying, staring up at me with curiosity.

"We did it," I whispered to him, smiling down into his wide eyes. "First deal closed, kiddo."

A soft rustle came from the sofa. Maren was watching us, propped up on one elbow. The shadows under her eyes were still prominent, but the harsh edge had softened.

"You didn't put the diaper on backward," she noted, a faint trace of amusement in her voice. "I'm impressed."

"I run a Fortune 500 company, Maren. I figured the sticky tabs go in the back," I teased gently, walking over and sitting on the edge of the couch.

She sat up, pulling her knees to her chest. "Why are you really here, Everett? You drove three hours in a snowstorm on Christmas Eve. You didn't know about Leo. Why did you come?"

I looked down at our son, resting peacefully in the crook of my arm.

"Because my penthouse felt like a tomb," I admitted, my voice dropping. "Because every time I closed a billion-dollar acquisition, I wanted to pick up the phone and hear your voice, only to remember you were gone. Because my mother hosted an extravagant holiday gala tonight with every socialite in Manhattan, and the only person I wanted to see was the woman who used to paint my hands green when we were making Christmas wreaths."

Maren looked away, her throat bobbing as she swallowed back emotion.

"I thought you had moved on," I continued quietly. "When I saw the decorated tree through your window from my car, I thought someone else was sitting here with you. The thought of another man taking care of you nearly drove me insane. But the truth is... I didn't deserve you then. And looking at what my mother put you through, I don't deserve you now."

"Everett..."

"I'm not leaving you alone in this, Maren," I said fiercely, leaning forward. "You don't have to take me back. You don't ever have to love me again. But I will provide everything for you and Leo. I will tear down every lie my mother told, and I will be the father this boy needs. Even if I have to sleep on your porch every night to prove it."

Maren watched me for a long time. The grandfather clock in the corner struck five. Outside, dawn was beginning to paint the snow-covered street in shades of pale rose and gold.

"Christmas morning," she murmured.

"Merry Christmas, Maren," I whispered back.
