First of all I do not know if some things will count as a spoiler. Second it is probably first time when I will mention a lot of cast in review, so let's go:
Yoo Seung Ho - he was the reason why I chose this drama cause I really liked him in My strange hero, he has such a cute smile (that make me want to see him act with Park Bo Young), he played really good, his sad, puppy eyes, also chemistry was cute
Chae Soo Bin - it turned out I already watch something with her (Sweet&Sour), she was much more memorable here, she played really cute and adorable character, chemistry was good, even with her character's ex
Uhm Ki Joon - I did not expect that I would like his character, in the end his story and romance with Pi were one of my favourite plots
Park Se Wan - she played really fun character, I already watched her in So not worth it and as far as I liked her there, here she literally stole the show, also when she straighten her hair she reminded me of Jo Bo Ah in My strange hero and now I need her as main lead with Yoo Seung Ho
Lee Min Ji, Seo Dong Won and Go Geon Han - were so easy to like, also Go Geon Han's english was so nice
Kang Ki Young - It is always nice to see some actor in drama when you do not expect him, I am so happy that in the end he turned out as a good person, also chemistry Hwang Seung Eon was so good - she played really nice character - need them as main leads
Also nice to see Choi Dong Goo after The judge from hell - his character was a little like mischievous puppy.
If you survive praising the cast then I move on to the plot - it was something new and at the same time nothing original, but was so easy to watch, I do not even know how fast I moved through it. It is worth watching, especially when you want to watch something light.
