I was really thinking this drama would be boring. Fyi, I just finished watched Descendant of the Sun when I started to watch it. It was like (cultural term: culture shock) a shock when I watched this japanese drama. Also, I was really thinking the plot would not be a complicated just like korean drama. Yet, I kept watching. My motivation to watch it was because the female protagonist (I just knew her name is Kawaguchi Haruna when I wrote this review) is so cute, so-my-type, and... I love both japanese and korean drama which has cute and so-my-type female main character. Until half of whole episodes, I was still thinking the ending could be predicted. But! Yea, I can't write a spoiler here.
