Guys, I really don't wanna reread this. Please can someone just summarise what the deal is...

Minjae hit Jungwoo (oldest) with vase in the past. The reasons are unknown. The past is secret between them. You will learn that later.
Junghyuk hates Minjae because he hurts his hyung and also because he doesnt want to share him with his step brothers.

Thanks. Someone tell Junghyuk that no-one wants his hyung.

U are welcome. Lol.
