In an unexpected but heartwarming announcement, Girls' Day member and actress Minah, 32, and actor On Joo-wan, 42, have revealed they will be tying the knot this coming November. The news, which took many fans and industry insiders by surprise, was confirmed on July 4, 2025, by both their agencies, SM C&C and Huayi Brothers Entertainment, marking the beginning of a new chapter for the couple after years of a quietly blossoming relationship.
Their story began nearly a decade ago in 2016 when the two actors first crossed paths on the set of the SBS drama Beautiful Gong Shim. While they weren’t romantically involved at that time, their connection as colleagues laid the foundation for what would eventually become a deep bond. It wasn’t until 2021, when they reunited for the musical Those Days, that their relationship took a more intimate turn, evolving from long-time acquaintances and industry peers into a loving couple.
Sources close to the couple revealed that their romance had been an open secret since 2024, though the pair chose to keep it out of the public eye until now. This discretion makes their announcement all the more striking, as there were no prior dating rumors or public displays of affection that typically accompany celebrity relationships. Their decision to marry appears to be the natural progression of a sincere and enduring partnership.
Their relationship was tested and strengthened during a difficult time last year when Minah suffered the loss of her father. On Joo-wan reportedly stood steadfastly by her side throughout the funeral proceedings, providing emotional support and comfort. A close insider shared, "On Joo-wan was there throughout the entire period, showing his unwavering support. Their hearts for each other are special, and after a long period of dating, they are now ready to marry this winter." This touching detail underscores the depth of their commitment.
Minah herself expressed her feelings about the marriage in a heartfelt handwritten letter posted on her fan cafe. She spoke candidly about the challenge of sharing such personal news, explaining, "I really struggled with how to break this story. I had imagined telling it beautifully when the time was right, but it didn’t go as planned, so I hurried to write this." She reflected nostalgically on her journey with her fans, affectionately known as "Daisies," likening the announcement to retrieving a treasured item from an old drawer. "We were truly passionate back then," she wrote, recalling the early days of her career and the support that helped her endure.
Minah acknowledged the vital role her fans have played in her life, stating, "You are my time and my life. The precious love and support you’ve given me have allowed me to live warmly and keep moving forward." She pledged to continue working hard to repay their affection and shared her joy in having "the closest person"—a clear reference to On Joo-wan—by her side to support her steadfastly. "I will keep challenging myself and protecting my family while receiving your heartfelt support," she promised, closing her letter with a warm call for her fans to celebrate this new chapter with her.
Both Minah and On Joo-wan have robust careers in the entertainment industry. Minah debuted as a member of the popular girl group Girls' Day in 2010 before branching into acting with roles in dramas such as Beautiful Gong Shim, Absolute Boyfriend, and the streaming series Deliveryman. She is now the second member of Girls' Day to marry, following Sojin, who wed actor Lee Dong-ha in 2023. The group recently reunited for their 15th anniversary, sparking renewed interest in their individual lives and careers.
On Joo-wan began his acting journey much earlier, debuting in 2002 with the drama Rustic Period. He gained wider recognition through the KBS 2TV entertainment show Rosemary's War in 2004. His filmography includes notable titles such as The Peter Pan Formula, The Taste of Money, and Human Addiction, alongside acclaimed television dramas like SBS’s Punch and Penthouse. Currently, he is reconnecting with audiences through the musical Mahagony, marking his return to the stage after a three-year hiatus.
The couple’s wedding will be an intimate affair, held privately with only close family members and relatives in attendance. Both agencies have asked for understanding regarding the low-profile nature of the ceremony, emphasizing the couple's wish to celebrate this milestone quietly amid their busy professional lives.
Their union is a testament to the enduring power of shared passion and trust in the often fast-paced and public world of entertainment. As one insider noted, "Both Minah and On Joo-wan share a deep passion for acting, which has been a common ground for them. Their long careers in the industry have allowed them to build a foundation of trust and mutual support, leading naturally to marriage."
With the wedding set for November 2025, fans and colleagues alike are eagerly anticipating this joyful celebration. Minah and On Joo-wan’s story, marked by years of quiet companionship and mutual respect, offers a refreshing glimpse into the personal lives behind the spotlight. It’s a reminder that even in the whirlwind of fame, genuine love and commitment can flourish and endure.
