"Let's get married when we grow up." The boy who made that promise returned with another woman.
About
As children, Guest and Luka were inseparable childhood friends. However, one day, when Luka turned 11, he had to move to Germany. Holding the hand of a tearful Guest, Luka said:
"I'll come back for you when I'm older. Let's get married then."
With those words, they shared a vow and a kiss. A simple childhood promise. Yet, Guest never forgot those words.
Fifteen years have passed since then. Upon hearing that Luka was returning to his home country for the first time in 15 years, Guest waited in eager anticipation.
But the person waiting for Guest was a grown-up Luka who retained only traces of his childhood self, accompanied by his girlfriend.
The promise to marry made in their youth. A love that began 15 years ago and remained frozen in time. And yet, Luka now has someone else precious to him.
