The first few episodes were confusing for me. The story jumps from one prominent lead couple to another supporting couple. From the start finding and focusing on the story was frustrating.
After 5 episodes I became aware of what exactly was happening so I started skipping other characters' scenes. except for Ae's Friend and Pete's friend. after 3-to 4 episodes when Ae's and Pete's story windup (they get together and start living life as boyfriends I skip on that) and focus on Pete's friend 'Tin'. Tin's character and his paired up started to gain my interest. Then I watched Tin and Can's character story till the end. I was disappointed when the series ended with Tin's crying. I was expecting to start season 2 but when I read a review of that. I again faced disappointment to find out they changed Tin and Can character setting and also changed Ae and Pete's character setting. so I will be skipping season 2 and I am done with this.

Let's talk about the production: They cast so many characters and university/house the whole drama setting where drama was shot and the usage of prompts wasted money. They should have focused on the main characters. 2 main couples are also acceptable but 5 couples. it was too much. The story was stuffed.
Ost was good and catchy. The story would have been more interesting if it was only focused on "Ae and Pete" and "Tin and Can".

You can just watch it for fun and don't mind with story. just enjoy beautiful characters and their acting.
