Fr. I want a side story with him, they're making him too sympathetic even tho he's a bad person. I'd be happy to see more of him as long as he's not romantically involved with the kid.

The thing is that Kim Dokja represents the reader in all of us, and now the reader is given the opportunity to touch and to alter the fate of an innocent character who was bound to be hurt beyond recognition and change for the worse. He may have simply taken a liking to her as she is just a child, and may be projecting the hurt and suffering he has himself suffered in the younger years of his life. From my understanding of Kim Dokja, he is a compassionate person and wishes to save everyone if possible. Also, the fact that those little kids are bound to be extremely powerful plays in his favour.
But I could be wrong

and also, aint shin yoosung bound to be stronger when she grows older?

she even became one of the disasters with how strong she is as an adult~

where as gilyoung, it is an advantage to have him when there are insect monster, however shin yoosung's ability is not just to control a monster, but she also has other abilities when she become an adult~

but i agree that it is dokja's attachment with yoosungs lifestory that he chose her~ her skills are add-ons, he desperately wants to protect yoosung, even her adult 'disaster' spirit became a dokaebi that dokja raised`

I’m glad you understood me and I absolutely agree with you (⌒▽⌒) I, myself, have taken a liking to her and I am looking forward to her growth
