This was a cute watch for me. I liked the fact that it was short, a nice change of pace and not much of an investment. It's not an original story by any means, but it was sweet. Being a short series, it felt rushed, especially since they had two couples to tell us about.

What I liked:
Kim So Hyun as Hong Ju. She is such a cutie, and I really enjoy watching her.
Chae Jong Hyeop as Hu Yeong. I've liked him in other works, and for the most part I enjoyed him (see below).
Yun Ji On as Jun Ho. I loved him in Tomorrow, but to me, his storyline seemed very forced.
Hwang Sung Bin as the PE teacher. He was terrific! I loved his straight, military demeanor and how out of his element he was with the 2FL.
I'm a sucker for when the man falls first, and we got it in both couples.
Chemistry, for the most part, was good. I hate to keep using the word "cute", but that's the thought I had as I watched it.
Second couple. I loved the second couple. They were very amusing. However, there was a lot of time spent on them, which took away from the main couple, but maybe that's okay.
I liked the friend with the restaurant and how he was trying to play matchmaker.

What, to me, could have been better:
At times, Chae Jong Hyeop's acting seemed a little forced, especially when he was hugging her and they focused on his face. His expression was totally blank, and his body language was stiff.
So much drinking!!!
Her leg injury - she's limping one minute, the next she's not, then back to limping, then the boot is gone and she's walking like she was never injured!
