At first, I thought that this drama will be similar to Extraordinary You, but actually it brings different taste. I even like it more than Extraordinary You because I like the characters of both FL and ML in this drama more. Their characters are really more favourable to me. I'm sorry for the comparison, but I think it may help audiences decide whether to watch it or not.

Story
It makes your heart fluttered. I've been watching so many kdramas since Boys over Flower era, but this drama makes my heart fluttered the most in all time. At a few episodes before the end, I also cried while being emotional with the drama. There is no part making me feel bored at all while watching it. Instead, it was so addicted that I cannot stop watching. I even had meals late and slept late to watch this.

Acting
Actors and actresses are quite new to acting, but ML and FL perfectly portray their chemistry that make audiences' heart seriously fluttered, so they have shown almost perfect acting skills. On top of that, their visual is so attractive. I hope they will have a bright future. I will watch them again if they act as a main role in future dramas.

Music
Music in this drama is not bad. It suits the drama perfectly except that it's not so addictive.

Rewatch
I'm already watching it again now because I cannot get over it.

In overall, it's a must watch for those who like school dramas or fantasy dramas.
