Timeline of S2
I know season 2 is only 8 episodes long, but everything felt too rushed. The show starts after winter break, so around the first week of January and in South Korea, the school year typically ends in February, so it's safe to assume everything takes place in 1-2 months.
With everything that takes place it feels like the characters move on and get over things WAY too quickly. It feels like none of the character's actions have any real consequences because everyone forgets about it in a few days or forgives the other person too quickly when a new problem arises. It just makes it hard to care and takes out the anticipation when you know every event won't have much of an impact overall anyway.
