I am not misunderstanding.
I am simply referencing that IF the stepdad's conscious is alive, he would probably enjoy seeing the rumination of those who tormented him. In fact, he might have welcomed the demi drake into his body for revenge if he was indeed dying.
The drake says the stepfather is dead, but we have no solid proof of that.
And I really would like to see more things from his prospective. The memories are really interesting, as I've pointed out before.
Why would he "buy" a family, especially if he hated them? I want more information.
The father had desires for Muyeon's mother since she made him feel like a man worthy of love while his work was dehumanizing him and his masculinity. That's why he would get mad at Muyeon when he would come because he wanted more time with the mom, since he knew his time was limited and would have go back to that shithell of work.

Now I want the memories of the stepfather.
Why did he pay Muyeon's mom to act like "family"? What did he get out if it?
Also, I bet the stepdad is having a grand time of being a demi drake and killing all these fuckers who made his life miserable when he was alive.
I need more memories now~
