It was revealed that Mir, formerly of MBLAQ, held a private wedding ceremony last December at a wedding hall in Seongnam, Gyeonggi Province, with a non-celebrity woman one year older than him. The wedding was quietly conducted with only family, relatives, and close acquaintances in attendance.

Before the wedding, Mir shared his thoughts, saying, "I have met a precious connection and tied the knot as a couple. We will cherish and respect each other and live sincerely."

After the wedding, Kim Jang-hoon, who performed the congratulatory song, posted a video from the event on SNS, which led to the bride's face being revealed. Following the controversy, Kim Jang-hoon deleted the post and issued an apology.

Until now, only the information that the bride was a "non-celebrity one year older" had been officially disclosed, but recently, through Ko Eun-ah's YouTube channel "Bangga-ne," it was revealed that the bride is a Pilates instructor. In the video, Ko Eun-ah visits the center to learn Pilates, and the center is introduced as being run by Ko Eun-ah's sister-in-law. In the video, Ko Eun-ah and her sister-in-law create a cheerful atmosphere and show a friendly relationship.

The sister-in-law demonstrated professional class instruction and bright energy, and the video also showed Ko Eun-ah performing Pilates movements. This revealed that Mir's wife had been comfortably mingling with the family even before the marriage.
