This drama is a hilarious play on stereotypical boys love cliche tropes, but at the same time to have its very own story which develops itself finely. I wish they had a second season made.
The casting also made me very happy with people I knew.
Choi Woosik (A lot of people know him from Train to Busan)
Jang Kiyong (From We Broke Up)
Irene (Red Velvet)
Jang Yoo Sang (Plays as Kwangsoo, the brother, in EXO Next Door)

All of their acting was pretty impressive, Irene's was a little awkward and stiff, but I really love the girl and she'll probably get better at it in the future.
