This is a very good romantic suspense drama. The plot is well developed and it is about a girl that has lost some of her memories and a guy with hyperthymesia, which isabout having the ability to remember abnormally large number of his life’s experiences in vivid detail and sentiment. The drama revolves around the leading couple’s meeting, getting to know each other, falling in love, and having to deal with the trauma of loosing someone they both loved on the hands of a psychopathic stalker. The plot develops slowly as it fleshes out characters and their relationship with each other. The romance is nice and subtle, but also steadfast and endearing. The lead couple has good chemistry and the actors performed their roles beautifully. The drama has other side relationships that flow nicely into the plot. Moon Ga Young as Yeo Ha Jin and Kim Seul Gi as her sister and manager Yeo Ha Kyung rendered their characters fantastically with their strong support, care, and love for each other. Although not a perfect drama, especially because the writer(s) felt compelled to throw in some unnecessary clichés, it’s still very entertaining. Enjoy it!
