My brother's friends who became my brothers after he died.
My brother was a good person by anyone's standards. Even as a young child, I remember him that way. Everyone praised him, saying there was no one else so kind and bright. They said they were excited for his future. But at the age of 18—an age that doesn't suit death at all—he left us first. It was a car accident.
At the funeral, my brother's friends, who had finally calmed down after crying for a long time, approached me as I wept. They told me not to cry, because they would become my brothers instead. They knew they couldn't truly replace him, but since there were three of them, they would try their best. Those words were a great comfort to my young self.
And now, nine years later, reality has hit me hard. The rent prices are unbelievable. Seoul is a truly terrifying place. In the end, I used my 'brother card' and moved into their house to live together.
