Honestly I would be a big liar if I said it’s good, because it’s not good. IT’S PERFECT AND EXCEPTIONAL!!! The idea of the disease alone is mind blowing, combined with the acting of the cast especially the main characters, it’s just perfectly synchronised. Also the romance is amazing and it’s one of the few kdramas that brings an excitement to my heart. After each episode I find myself tearing my clothes waiting for the next release. If their is more than 5 stars I would for sure give it the maximum because it’s so underrated and I think it deserves to be one of the best kramas no one of the best kramas in the world especially considering all the effort put into the drama.
