The OST!!! Their One Way Ticket imaginary dance, it was soooo good, it gave me goosebumps!! Fell for Snow Drop not just because of Jung Hae In, but because of the plot, storyline & quiet-kilig vibe - Soo Ho reminds me of Capt. Ri Jeong Hyeok (maybe because both of them are from the North)
Snow Drop also triggers my curiousity. Yes, the whole thing is so unpredictable - I am so attached to this Kdrama.
The late 1980s vibe -- 1987 to be exact. the vintage phones, casette tapes & casette, OST (One Way Ticket), frizzy hairdos, 80s get-ups etc..
I highly recommend Snow Drop especially to OG Kdramarists who will never get bored of the North-South & political conflicts storylines.
