do not believe those who rated it with less than 4 stars their opinion does not matter cuz its senseless this the best k drama I've ever watched (watched 65+ kdramas) it reached all my expectations though the ending was rushed it was very satisfying and the chemistry between the leads is too good despite having less screen time with romance the insane plot twists and cliffhangers after each episode was the key to keep me hooked I guess and I feel if it was brought by Netflix then the drama would have gained more success as they provide viewers with fun challenges among the actors and the bts and the casting director knows what they're doing the storyline is amazing writer must be a cinematic genius and about the ost it's so addicting I love it i overall review I loved each n every second of this drama too good to be true
