Good:
Character development
- The main characters and side characters grew as the drama progressed in a realistic fashion. While at times the main actress's decisions did not make sense, it was not detrimental.
Moral
- The issue of bullying in Korea (and I would assume the rest of SE Asia) is slowly coming to the forefront and therefore, this show brings in a new perspective to the issue.
Yeon woo
- Loved her in Pegasus Market and Momoland. Happy to see her have more screen time.
Music
-Was good enough for me to look for the OST. Not the pinnacle of OST's but close enough.

Meh:
Story
-Nothing ground breaking. Quite vanilla but it was still sweet.
-There was a lot more they could have delved deeper into such as main actresses family relationships.
-Teacher's were essentially non-existent in the drama, which is slightly unbelievable but at least subway made an appearance.
Characters could have been fleshed out a bit more.

Bad:
Consequences of actions
-Main protagonist (actual bully) remains unpunished. That story arc is not concluded.
-Secondary protagonist was quickly wrapped up with no real conclusion.
-Main Female lead's negative actions were quickly brush aside and unpunished.
Product placement was super obvious

Overall, it was an easy to digest drama with the super cute Yeon Woo.
8.5 mydramalist rating = it is a watch. Low/non-existent re-watch value.
