I was loved this kind of youth cdramas. After Wifty (When I fly towards you) I felt an emptiness and this cdrama filled it. I thought there would be no drama that focused on friendship like Wifty, and I was wrong. By the way, I don't understand why you gave it such a low rating. it must 9.0 rating. I felt every emotion with them (laughed, cried, had fun, etc.) I especially continued watching for Han Suhai and Ting Ting. I had fun in every scene of them. Throughout the 21 episodes, I never regretted starting. I hope there will be more youth cdramas like this...
