This is a unique, deep and complicated story that many will not understand. if you like complex stories that keep you questioning the morality and sanity of characters, then I highly recommend it (unless u hate love triangle) this drama had one of the most heart-wrenching and epic love triangles that i've ever seen, It was also one of the Kdramas where you really couldn’t predict who the female lead was going to end up with, some of ppl say that they didn't even get who was the main male lead; in my opinion the whole story revolved around jichul/jbs revenge and his love but in most of kdramas If the female lead is in love with someone, you can conclude that that person is the main male lead and thats what confused them at first, but jk was the main one as he was mentioned first in the posters and news, anyway this drama is different from other kdramas give it a chance and don't pay attention to negative comments or how it is rated because everyone has a different taste. Im satisfied and i loved the ending so much! <3
