Go into this with low expectations. Its a short (13 mins per ep ,22 eps in total) sweet school drama evolving around typical teeanger armed topics. Such as acceptance/ outcast in class and social media and sweet buds of romance growing and blooming on the way.

Pros: -sweet little story that touches deep youth worries
-nice OST
-good looking young actors
-short episodes
Cons: -acting is so-so as for many actors this is their first drama
-a lot of scenes that are repeatedly shown in flashbacks and such
-short episodes, limits of character and story development

Just give it a try, the eps are short anyway so you will not "loose" to much time if you don't like.
