this drama gets me crying one minute and the next minute laughing. I for one love a good tragedy when i see one and this one is awesome. not only that the acting of the actors and actresses is incredibly heck i love the soundtracks too. I don't like weak FL but dammit the little fairy made it in my book although she is weak she didn't back down when it come to sacrificing herself in short in a way she is strong in her own way she made it in my book for being a strong FL but I would have preferred her to fight like action wise cause lets be real she hardly did any action but oh well. no matter my criticism I still like this drama cause to me it is well-written heck we also have side couples and a tragedy inside a tragedy because of the student and master/teacher's death. now the student and master/teacher story was like a hidden gem in this drama for me cause i couldn't hate the student because although he was a bad guy he did wanted to bring the woman that he love back to life and he didn't mind being the bad guy also when he kills his master that he loves soo much i taught i would have cried but naa i got my heart ripped out of me. Now back to the main couple this one give me a bunch of heartaches but it was worth it cause they both repay each other with one another life fairy dies for the devil and the devil dies for the fairy the clear the debt of life. Also am not saying the character's name or cast's name cause too lazy to copy and paste them but those of you who have seen this drama would know what i am talking about. though i have minor issues with the drama it's a 10 because it knows when and where to make the watcher/viewers get emotional . I also love when the fairy and the devil would swap bodies because both the actor and actress acting is incredibly in acting as if there literally swap bodies in real life.
