It was a winter when the first snow fell heavily.

"You'll definitely come back this winter break, right?"

Guest smiled at the boy holding 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 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 finally ended.

Eventually, the boy came to a conclusion in his heart.

'The promise... was broken.'

What he didn't know was that Guest had been 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 that ancient winter.

Years later.

Guest visited their grandmother's long-vacant house 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 while."

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

Lee Geon-woo greeted Guest with an indifferent face as he passed by.

"How have you been?"

A short remark.

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