My wife is a nurse.
Her duties are irregular, and there are weeks when she only comes home three nights a week. I know she has a tough job, so I choose to understand rather than complain. But in recent months, something has seemed different about her.

When she comes home, she immediately stares at her phone.

Back then, she was still enthusiastic about cooking and looking forward to our dinners together, but now, it seems like the warmth of her presence has gradually faded. I feel a little hurt, but I just think about it — that’s how it is in the medical field, time for yourself is rare.

But one night during a heavy rain, something unexpected happened. I saw her wearing black socks — clearly a size larger.

When I asked, she just smiled and said:

— “It’s cold in the hospital.

I just bought some across the street, there are no women’s.”

It seems reasonable, but there is some pain that I can’t explain.
That night, while it was still raining outside, I hugged him to find warmth. He gently pushed my hand away, saying he was tired. I turned over and slowly fell asleep, but in my mind, the image of the black socks and his avoidance kept replaying in my mind.

Until suddenly my cellphone rang — ting!.

I turned slightly and saw him get up, reading the message. In a flash, I read a few words:
“Come downstairs.”

My chest pounded.

Who would message him at this hour? It couldn’t just be a coworker.

I pretended to be asleep while watching his every move.

After a few minutes, he slowly got off the bed and left the room. I followed him, silently, my anger swallowed by nervousness. On the stairs, I heard his soft voice:
“Don’t tell my wife…”

It felt like something was squeezing my heart.
Those words echoed in my mind all night, until before I knew it, the sun had risen.

The next day, I woke up to the sunlight shining into our room.

Next to my pillow, there was a shiny key and a small piece of paper. Written in familiar handwriting:

“Happy birthday, my love.

I saved for a year and even borrowed a little to buy you a car. The nights I was away – those were the times I took care of the paperwork and the search.

I hope you like it.”

I stared at the paper, my hands shaking.

The nights of doubt, the secret messages, even the black socks – it turned out to be all part of a surprise. Outside, the mist continued. But inside, there was a strange warmth.

I held the key, and my tears slowly dripped onto the paper — tears of relief, of understanding, and of love that was stronger than any rain.
