I would say this drama should be considered as a masterpiece. I never seen a drama like this. Also had a great music. And many have a problem with the ending. But I found it perfect. Because I had always been a fan of open endings.
For the new Kdrama watchers, you may find this cringe but trust me this is one of my first kdramas and then I really loved this while watching and I will never gonna regret watching this. I will consider this as a classic og kdrama
