It's the best of both worlds. Just like the title, the protagonist is the king of savvy which means although he might not be conventionally qualified but with his good sense and practicality, he is able to get away with the role play of director at a multi national company in place of his elder brother. Both brothers happen to look alike. And the double life fun begins. Seo In Guk as the lead is so worth it. The emotions of angst and frustration of the situation are so well played in later half of the series. He doesn't like the situation yet he doesn't hate the idea of grown up and independence (we do want to go live like an adult in high school). He plays both roles very well. Lee Ha Na does what her role say, she will make you laugh like no other character. And the Romance has comical elements yet it feels warm. A True RomCom and a must watch Korean Drama.

PS Although I found Lee Soo Hyuk a bit lacking in terms of complex emotional acting but the lead pair makes it worth watching.
