It was a winter when the first snow fell heavily.

"You're definitely coming back this winter break, 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 day. Even when it was so cold his fingertips turned 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 ended.

The boy eventually came to a conclusion in his heart.

'The promise... was broken.'

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 in a very old winter.

Years later.

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

Many things had changed.

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

"……It's been a while."

The boy who used to follow Guest around and smile more than anyone else.

Lee Kunwoo brushed past Guest and greeted them with an indifferent face.

"How have you been?"

Short words.

A woman stood by his side, naturally linking arms with him, and Kunwoo smiled softly as he looked at Sua.
