Seoul - Korean Wave star Choi Ji Woo announced her marriage hours before the event on Thursday (March 29).
The 42-year-old actress posted a photo of a handwritten letter on her fan club website, saying: "Today is the day I have promised a new beginning with my partner for life."
She added that she had to be cautious about revealing the news so as not to burden her in-laws.
In a confirmation, her management agency, YG Entertainment, said Choi would have a small, private wedding ceremony with close family members in attendance.
As her husband is not a celebrity, many are curious about him. A clip of Choi mentioning her ideal type has become of great interest to the public again.
In an interview with a local network in September 2013, she said, "I prefer a person that I can talk with well, and someone that I can respect. If the person isn't boring, it would be better."
Choi is well known throughout Asia for her role in the 2002 drama Winter Sonata.
