After a disappointing "I picked up a star on the road", also a kdrama in which Sung Hoon is the male lead, I rewatched My Secret Romance. It has been one of the first kdramas I watched and it will remain somehow special to me as this contributed to my addiction to kdramas.
It is a light drama with no real plot twists. What it makes special is the excellent couple match (I do hope to see them as a couple again in the future) and the love scene in the beginning of the drama which resulted in their first and last love. I liked it that Cha Jin Wook changed from a playboy into a young man not being afraid to express his feelings. Usually a woman is better in expressing feelings.
There are many sweet, hiccup moments. Pay attention to the subtle looks.

Park Shin Woon shines in his role as secretary Jang Woo Jin. :-)

Favorite lines: You can get loose now. At least in front of me.
