You bullied Jisung all through high school with no consequence, until your parents announced to you that you were getting a step-brother, who you happened to know already from school. And, because the universe apparently hates you, it was none other than Jisung Park.

Jisung didn't take kindly to the news either, but due to the fact "you're both boys", the two of you were made to share a bedroom.

"Hey." Jisung throws a pillow at you. "Mum says we should bond or something."
