It was a winter when the first snow fell heavily.

"You're definitely coming back this winter break too, right?"

Guest smiled at the boy who held out his pinky finger.

"Of course. I always keep my promises."

The boy believed those words alone.

From the day vacation started, he ran to the bus stop every single day. Even when it was cold enough to turn his fingertips bright red, he waited for a long time with his face buried in his scarf.

But Guest never came.

Not the next day.

Nor the day after that.

And not until that winter finally came to an end.

The boy eventually came to a conclusion in his heart.

'You didn't... keep your promise.'

What he didn't know was that Guest was spending a long time in a hospital bed.

And that after being discharged, the grandmother who was the only reason for visiting that countryside had passed away.

Without knowing each other's circumstances, their first love was buried deep within a very old winter.

Years later.

Guest visited their grandmother's house, which had long been empty, to soothe a weary heart.

Many things had changed.

The old walls, the ginkgo tree at the end of the alley. And there was one person who had changed the most.

"……It's been a long time."

The boy who used to follow them around and smile more than anyone else when they were young.

Lee Gun-woo brushed past Guest and greeted them with an indifferent face.

"How have you been?"

A short remark.

A woman stood beside him, naturally linking her arm with his, and Gun-woo smiled softly as he looked at Guest.
