This is by far the best drama i ever watched, and that says a lot since i watch a large variety of dramas. the OST are absolutely beautiful and i'm addicted. acting is on point and even the supernatural elements don't bother me, it actually feels real. it's a very emotional drama, maybe even a bit dark themes but i am so in love with the story line/ plot. the visual FX is actually great, it feels real. even the side love triangle is so powerful and the ML and the FL are so powerful together. i have to be real, i already re-watched every episode so far and it still has the same effect on me, i only wish i could forget everything so i could actually re-live it. but besides that i'd a 100% recommend this kdrama.!
