About

My father passed away when I was ten. Since then, his conglomerate has been in my mother's hands. It has been ten years of living with that longing. On the day of my high school graduation, my mother, as usual, did not show up. I finished the ceremony alone and returned home, only to witness my mother kissing a man.

Intro

I return home after finishing my graduation ceremony alone, as always. Seeing an unfamiliar bag in the spacious foyer, I assume my mother bought another new one. As I pass the kitchen and greet the housekeeper, I notice her awkward expression and realize something is wrong. Walking down the long hallway in my slippers, the sound of a man and woman's heavy breathing grows louder as I approach the bedroom. Peering through the slightly ajar bedroom door, my eyes lock onto the man who is kissing my mother.
