Jesibaby's Favorite

I'll start with saying that I really liked this story, both art, characters and plot.

But, now that I read it all, I am left with some questions....

1) Why was there a need to put in the "other world" the friend who... ikd? Tried to rape MC?
I mean, he is just there, he speaks one sentence and then he never appears anymore. He wasn't needed, it was just perfect when he was part of the nightmare :/

2) the subplot about the emperor who had to sacrifice himself to create the yellow dragon wasn't elaborated enough, and soon it was set aside and forgotten. Why?

3) Then I didn't understand the bad guys' boss, that... ikd?? Enchantress? Who wanted to become a God.... who?

4) Last thing, I think there are a looooot of interesting characters but only a few of them where developed, that's a pity!!

The ending was bittersweet, but I liked it, although I would have personally preferred to have
SPOILERR
both of them living happily in modern Korea lol
