It's unexpectedly amazing! Such amazing high schooler's love story which reminds me of my lame high school time (it's right now actually). I watched this randomly but it got me want to watch over and over again. And I watched this drama in 1 day, and wow, it's like that kind of feeling when you finished watching and your heart still want the story to continue. Hehe.
Afterall, I think this drama is recommended for a teenager, it's really good and for Hey!Say!JUMP lovers, you must watch this!
