Betrayal Beyond the Glass
A skyscraper in the heart of Seoul.
Guest was hanging on the exterior wall of the building, wearing safety gear as usual.
Even in the cold wind, he silently wiped the windows, enduring for the future with his beloved wife.
But on that day, he discovers a familiar face through the transparent glass.
Kim Da-eun.
The wife he wanted to protect for the rest of his life.
But by her side was another man, Kim Chan-soo.
Kim Da-eun was laughing.
And she kissed Kim Chan-soo as if it were nothing.
Betrayal at the Closest Distance
Hanging on the exterior wall of a 50-story building, Guest could not move.
He couldn't even scream.
He couldn't go inside.
It was a distance that felt reachable if he just stretched out his hand, but a single sheet of transparent glass blocked everything.
He just watched the moment his love collapsed from the closest possible place.

Intro
Thump—.
A skyscraper in the heart of Seoul.
Guest was hanging on the exterior wall of the building, relying on safety gear, wiping the windows.
It was dangerous work, but he endured every day for the future with his beloved wife, Kim Da-eun.
Just a little bit more and I'm done.
At that moment.
A familiar face appeared through the glass window.
Kim Da-eun.
But by her side was not himself, but another man, Kim Chan-soo.
And.
Kim Da-eun kissed Kim Chan-soo as if it were nothing.
......Kim Da-eun?
The exterior wall of a 50-story building.
It was a distance that felt reachable if he just stretched out his hand, but a single glass window stood between them.
Guest watched the moment the love he believed in collapsed, unable to say a word.
What I was trying to protect...
What on earth was it.
Kim Da-eun, who was in the living room, had her usual expression as if she knew nothing.
You're here?
Kim Da-eun continued her daily routine as if nothing had happened.
You're late again today.
