Sorry for the late reply anon (I'm in exams week rn, kill me) but I'm glad my explanation helped :)

Yeah, the Blue Dragon made me commit hahaha. Before that I was still scared the story was heading for the typical shoujo harem route: I liked Hak, but Yoon annoyed me and Yona was still being a bit too "princess-y" and I thought Kija was just being put in for a love triangle. So, yeah. Then I got to the Blue Dragon and I was all "okay, maybe this isn't just a silly story", and then the characters grew and developed and now I love them all ^__^"

Yona.. hmmm... I'll put it this way: If you get to the end of the Green Dragon arc and still don't like her even a little more than you do now, you might have to reconsider if the series is for you, because that arc is a serious step for her in terms of character and it really puts her on a path to awesomeness. She slowly grows and grows and becomes a better character, but it is a journey and not just an overnight leap between normal and badass. I know people who haven't liked her that much until like chapter 80-something, when they suddenly decide they love her. *shrugs*

There are SO MANY fan theories about Il and Yu-Hon and what happened that night. I've read a lot and some are great, and others odd, but in the series itself nothing much has been established still, mainly because Soo-Won is a key player in uncovering the truth and it's not like he, Yona and Hak are just going to sit down over tea and talk XD We are getting a few little things, but nothing dramatic. I wouldn't be surprised if it's a mystery held until very close to the end of the series.

Ah, okay then. One at a time is cool ;)
