I think it's too easy to think that the Orange Hyujin did it. It might also be the Red Hyujin, who seems to be quite a manipulative bastard. Although his feelings for the other one look true, everything in this manwha isn't what it seems to be so... where is the truth in all that?
I'm still convinced that Blue Hyujin is the real one but I feel like the author is wanting us to think like that and will completely blow our minds away at end XD
Well, that's what makes it a good manwha to read ε=ε=(ノ≧∇≦)ノ

You've just met him!!! You've spent a lot of time with Jamil, who loved and cherished you as much as his own life, but you betray him just like that because of some sweet words? I thought you were better than this Jan
I'm so sad because I loved that Manwha so far but... it's changing into something that I don't like at all so, I'll wait for it to be finished and come back to it later. I'm feeling so sad for Jamil right now...
Me being interested in the secondary couple as much as the main couple means that the author did a wonderful job at building her characters (O//W//O)
I hope everything will be alright for Chanwoo! I'm like MD, I don't like seeing him hurt or sad or tired! Give him all the love <3
