I don't even know how to start. I watched the series because I knew 2 actors who play there so I already had some expectations that it's gonna be good but this show is just amazing. The actors portrayed their roles so so good. I don't even have words to describe it. (I wish I could speak English fluently.) They moved my heart in a lot of scenes. I was shocked, I laughed, I cried. I fell in love with Shi Eun and Soo Ho friendship. It was so cute and pure and just so real. The series showed a lot of real teenagers problems the twist were so good. THE ENDING WAS JUST STRAIGHT PAIN. I mean I was happy that he didn't die but the scene when he "woke up". They just played with my feelings.
To sum up the show is in my top faves but we'll see after another season.
