This was recommended to me by friends, at the start of the CoVid19 self-quarantine (not lockdown yet). After having watched all the top rated U.S., U.K. Oz, Mexican, Spanish and other European series and waiting for the next season/s, I started to watch KDrama, for the first time ever, with this. And oh boy! Got me hooked at the first "annsaeyo"! Thoruoghly enjoyed this series, from storyline, acting, carefully chosen cast ensemble AND the original piano soundtrack!!! Phenomenal. Worldwide. Rewatch value? Beyond 10!
