The story is awesome!! It has fantasy with rom-com and a little bit of thriller which makes the plot interesting. The whole drama doesn't actually focus on the fact that the female main character is going to die in a year if the Marble isn't taken out by then. Also the scenes at school are realistic as you do usually see fake friends and players. Plus the friendship whether with the trio (Lee Dam, Do Jae-jin, and Choi Soo-kyung) or the love/hate friendship between Shin Woo-yeo and Yang Hye-sun are actually interesting and hilarious. Quite different from most gumiho dramas, this one is light-hearted. Add along the OSTs which perfectly fit into the drama!
