I am truly sorry to the daughter who has such an unworthy father

'I am truly sorry to the daughter who has such an unworthy father' originates from a statement made by Ko Seung-deok, a candidate in the 2014 Seoul Metropolitan Office of Education superintendent election. At the time, his daughter, Ko Candy, posted on Facebook that her father was not qualified to be the superintendent, which sparked controversy. As Ko Seung-deok's approval rating fell, he cried out during a campaign at Gangnam Station, saying, "I am truly sorry to the daughter who has such an unworthy father!" This scene drew attention from the media and the public, leading to numerous parodies and mashups on the internet.

In particular, a parody video called "Father Metal" gained great popularity. This video combined Ko Seung-deok's statement with metal music, creating unique humor by blending his desperate expression with the intense music. Subsequently, the phrase transformed into the format "I am truly sorry to OO who has such an unworthy XX" and was humorously applied in various situations, such as "I am truly sorry to the manager who has such an unworthy team member."

This expression spread rapidly through online communities and social media, not only in political and social contexts but also in various humorous everyday content. Moreover, such parody culture has become a way for the public to satirize and humorously interpret political events or social issues.
