Jock's step-brother [Taekook]

Prolouge

From his 20 years of living alone in a house, Jeongguk doesn't know how to care. Jeongguk didn't like his privacy invaded.

He likes to keep it all to himself, doesn't share his things. And he's doing the same thing for his new stepbrother, Kim Taehyung, who only wanted to live his life in peace.

But everything changes when their parents decided to make them live together for the sake of their studies.

And Jeongguk can't be more happier.
