The concepts in this drama were beautiful and unique and distinct. Eun Dan oh's character was straightforward, clever and amusing. I was overjoyed and jumped headfirst into this drama in the beginning. The overused loss of memory trope and repetitive scenes ruined this drama for me. The way Eun Dan Oh began to fall for Haru was also not likeable. It was not due to his personality as he hardly had any character development. It was more cliche like fate because he happened to make her heart beat fast a couple times. The ending was the worst as it broke all the basic logic and rules the comic world had introduced in the beginning. Haru's character could have done with so much more development. He seemed to pop up out of nowhere for no reason. This drama was a wasted potential. A lot more could have been made out of it. Eun Dan Oh's and Haru's chemistry was non-existent in my opinion and their romance screamed "forbidden love" in my face all the time. It was like they picked the 2 characters who would find it hardest to love each other and pushed them down a roller-coaster together. The unique plot made watching it worth it for me though.
