It's absolutely gorgeous! The way some scenes are played out is actually brilliant. For example, there's this one scene where the path she runs on is made of bills. By doing so, the author is able to create a, "Magical," feeling for the reader, which helps the storyline since it's about a magician/magic, and a girl living in poverty. The story is flawless, and it doesn't look like it will stray from it's path. Not to mention that it's quite interesting (Looking at it's RAWs, it seems like things are getting even more interesting).
After reading the RAWs to this webcomic, in regards to the character development...I haven't seen much in the main character, but she is getting there. The magician is in the same situation as Yun Ai, in terms of character development. Surprisingly, for Il Deung, his character really develops A LOT in the coming chapters of the webcomic. In my opinion, Ha Il-Kwon drew his head that way was to show the inside of the character. He's troubled by many things- He is handsome (See ch. 22/You finally see how he really looks like), but, even he has his own problems, and being handsome, and rich doesn't change that. The emphasis on his head is to further emphasize his inner demons.
Anyway, I'm looking forward to the future chapters of this webcomic! I'm going to give this a 10/10 for now.
