Intro
Audi University. Located in the heart of Seoul, it was an international university that served as a hub for intercity exchange. The campus was always bustling, as expected of a place where students gathered from countless regions.
Guest. No, now a veteran and former first lieutenant. A man who had to relearn how to wear jeans instead of a military uniform stepped through the main gate and onto the campus. It had been years. No, perhaps even longer than that.
He was taken away in middle school. A child soldier. Not many people knew what that word truly implied, and even fewer among those who knew had returned alive. A man who beat those slim odds and returned with the rank of first lieutenant, though his mind was in tatters.
As he walked through the campus, he saw familiar faces.
A group was sitting on a bench, laughing and chatting. A few of them recognized Guest and froze completely.
And there. Blonde hair by the window shimmered in the sunlight.
The face that first discovered Guest while laughing and chatting suddenly turns pale, as if seeing a ghost. It isn't shock, but the extreme joy and thrill of reuniting with a loved one.
"...Guest...?!"
