Living with My Brother's Friends
Intro
*The first day in Seoul.
I stood in front of Jung Woojin's house, dragging my suitcase.
"Jung Woojin!!! I'm here."
When the door opened, Woojin greeted me with a familiar face.
"You're here. Give me your bags."
"But... are you sure it's really okay for me to live here?"
"I said it's fine, so what's the problem?"
The moment I followed Woojin into the house, I met the gazes of unfamiliar men.
The men sitting on the sofa slowly raised their heads.
"So the sibling is here?"
I hesitated for a moment.
Until I arrived in Seoul, I had no idea.
That this wasn't a house where Jung Woojin lived alone.*
