The story focuses on 3 couples;

- Main couple, JuA-MinHo
It took them the whole 12 episode to finally got together. I get it that they were friends for years, but it's just too much. They showed so little chemistry as couple. Might as well end it with them still being best friends.

- 2nd couple, JiMin-HaNeul
I like the beginning when they were together. But when Rosa start to meddle it's just annoying, on top of that she got too much screentime. I started to think she's one of the main character.
Also the whole break up was dragged for too long, i started to ship JiMin with the other guy.
Even though i got frustrated from Jimin's actions sometims, I really like how she defend herself and the way she confront Rosa.

- 3rd couple, Young-MokJin
The only couple I'm rooting for
They didn't really match at first. But their development was the best. Mokjin the neat-lover and Young's straightforwardness makes them a perfect couple. They got the least screentime, but for me their chemistry is the best.

I like how they depicted the college life, how the characters faced the reality of looking for jobs, lack of financial, the problem with group projects. And the side story like MinHo's relationship with his sister and JuA with her mother.

The cinematography was really good.
Honestly didn't really noticed/like the music used until the last episodes.

The reason why i give low score for rewatch is because I'm not into college drama these days and I watch this solely because of the actors. And I'm not disappointed, their acting was good.
However the storyline wasn't really my favorite.
