Singer Kim Jong-kook has made private a YouTube video documenting his honeymoon. The video attracted attention due to a scene capturing the silhouette of his wife. On the 9th, Kim Jong-kook uploaded a video titled "Hotel Breakfast Workout" on his YouTube channel 'GYM JONG KOOK'. The video featured his honeymoon itinerary in Paris, France, along with his workout routine.

In the video, Kim Jong-kook began exercising at the hotel gym from 6 a.m. He said, "I thought I wouldn't have time, so I'm going to work out in advance," showing that he continued his exercise routine even while traveling. He continued his morning workout after moving to another hotel. Kim Jong-kook said, "People ask if there's a fight when you work out on your honeymoon, but I just go out and work out while my wife is sleeping." At the end of the video, a caption appeared saying, "I filmed this to answer questions; I woke up early in the morning to work out and traveled."

However, the controversy surrounding the video was not just about the workout. During a scene introducing the hotel room, a silhouette of a woman presumed to be Kim Jong-kook's wife briefly appeared on the window glass. Although her face or distinct features were not visible, netizens reacted by saying, "That's his wife." Subsequently, the video was unofficially set to private.

After the video was suddenly made private, some netizens responded, "It seems like it was taken down because they realized the wife was exposed." Kim Jong-kook has maintained a stance of not revealing his bride, and some believe this action reflects his wishes.

Kim Jong-kook held an unofficial wedding ceremony with a non-celebrity woman at a hotel in Seoul last September. The ceremony was limited to a minimal number of attendees, and no wedding photos or information about the bride were released. It was nicknamed the "tightest security wedding" online. Despite ongoing speculation about the bride, Kim Jong-kook dismissed it on a broadcast, saying, "Except for the gender, nothing else is correct."

On the KBS2 TV variety show 'Problematic Men in the Rooftop Room,' he mentioned about his wife, "She is not someone who works out. She is on the slim side." Yang Se-chan, who attended as a guest at the wedding, drew attention by saying, "Her shoulders are square, and she is tall."

Kim Jong-kook strictly controlled cameras at the wedding to prevent his wife's identity from being revealed to the public. This led to various rumors, but Kim Jong-kook neither clarified nor disclosed any information. This situation caused some negative reactions, labeling him as "overly cautious."

Speculation has arisen that Kim Jong-kook's decision to make the honeymoon video private stems from the burden of revealing his wife's silhouette. He appears to be considerate of his non-celebrity wife by not wanting to expose even a silhouette that could identify her. On the other hand, some believe Kim Jong-kook is excessively hiding his wife.

About ten days before the wedding, Kim Jong-kook surprised the public and entertainment industry colleagues by announcing his marriage to a non-celebrity woman. The wedding was conducted under strict security, and since then, interest has focused on his newlywed life and honeymoon. Attention is on what decision Kim Jong-kook will make regarding revealing his wife.
