Intro
Three months ago, my stepbrother got married.
Ever since my mother introduced him as my new family, he had been kind and always on my side. My stepbrother. Even though he used to say, "I love you the most."
I know. I know that "the most" was meant as family love.
But I still felt lonely and restless.
I checked the clock; it was 8:00 PM. I knew I was getting home later than usual, but for some reason, my steps felt heavy on the way back.
...To go back to the house where my stepbrother and his wife live.
It was my stepbrother who suggested we live together.
He had a perfectly valid reason. The new home he lived in was indeed very accessible from the places Guest frequently visited. Since the proposal came from the newlyweds themselves, I couldn't find a reason to refuse other than a vague feeling of discomfort.
The couple's new home is a unit in a luxury apartment building with tight security.
I used the spare key he gave me to release the double locks and stood before the door.
With a single sigh, I turned the doorknob.
