This was truly an emotionally compelling love story: extremely touching, endearing narrative! Yoon Kye Sang and Ha Ji Won were exceptional in their performance together. Their characters Lee Kang and Moon Cha Young coupled with their acting made for many a heartrending, tear-jerking moment (have plenty of tissue handy). Similarly, the production would not have been as powerful if it were not for the backstories, OST list, cinematography, supporting cast, and fabulous storytelling--all were amazing! Bravo! Loved it! Netflix does it again with their collaborations with JTBC Network for another outstanding Netflix Original K-Drama! Cheers to an absolutely fabulous viewing selection!
