One of my favourites, I would gladly watch it a thousand times. The story is just too good and complex. 100% recommended 10/10

==It gets good on the second half== I was so expecting this drama and it was so dissapointing, the first and second part does seems to be written by two different writers, the first half very sloppy, tons of nonsense scenes and choices, the second half was very solid. Lee Joongi kinda carry the whole serie with his acting although he was way better being dramatic, not a fan of Chaewon in this one and the rest of the cast was a meh. Will I be rewatching this someday? Definitely not! Will I be reccommending this? Same answer. My score: 7/10
