My first Korean horror drama and my favorite! The Story - Tragic and simple(in a good way) thats how i would describe this drama.. it was great, loved it! Acting/Cast - Great cast! Btob's Sungjae made me fall for his character, i would go for him anytime and that was before i even knew he was part of Btob, that's an idol with acting skills no doubt! :) The lead female was good you can't hate her, the villain on point. Music- many people had problems with it, that there was music when it wasnt needed but i loved that part because it was funny for me XD. Rewatch Value - When there is not that much good horror dramas that are actually a horror drama's there is no way this one cant have a high rating there i think 7.5 is good. Overall it was a great i never thought i would be so interested :)
