They are not revealed that part yet. But if you read the latest update, the farther's real son committed suicide because he can't stand the bullying anymore and minjar that cause that to happened. Idk actually, but this is my theory ╮(￣▽￣)╭
Minjae*
Minjae push him into the fire instead of helping him after the bully targeted him for standing up for minjae.
Was it mentioned how Minjae killed the dad's real son? Cause I don't remember that part (￣∇￣")
