Netiznes who are known for spotting the most insignificant and usually hard-to-see mistakes, found one in the SBS drama.

On the third episode of the drama that aired on February 14th, while Oh Soo (Jo In Sung) was out, Secretary Wang, who is On Young's stepmother, went through Oh Soo's things to confirm that he was in deed who he says he is.

In the scene, she took out his passport, his ID card, and his driver's license. On the documents, Oh Soo's date of birthday don't match. In his passport and ID card, it says that he was born in February 18, 1984, but in his driver’s license it says he was born on September 12, 1979.

However, Secretary Wang (and the drama editors) didn’t notice this either and the scene was over.

The drama that recently started, draw many viewers, as well a praises for the pot line, the great acting and its OST, that is sang by Super Junior's Yesung.
