On June 7, Seo shot a 4-under-par 68 in the final round of the 2026 KLPGA Tour event held at Seongmunan Country Club in Wonju, Gangwon Province, with five birdies and one bogey.
With a total score of 15-under 201, Seo edged out second-place Kim Min-sun, who finished at 14-under 202, by one stroke to secure her first win.
This victory propelled Seo from 11th to 1st place in the points standings. She also claimed a winner's prize of 270 million won, moving her from 10th to 1st place in the earnings rankings with a total of 535,747,571 won.
Seo made her KLPGA debut in 2024 and, although she did not win any tournaments last year, she finished as a runner-up in the K-Food Nolbu & Hwami Masters and the S-Oil Championship, earning her the Rookie of the Year award. This year, she showcased her skills with a second-place finish at the Siena Open in April and a third-place finish at the E1 Charity Open in May.
After four top-three finishes since her debut, Seo finally secured her first victory. Overcome with emotion, she bit her lip and shed tears after the win, even experiencing a nosebleed afterward.
In a post-match interview, Seo said, "This was my fourth time in the championship group. I finished as a runner-up in the previous three. I thought it would be too upsetting to finish second again, so I worked hard to aim for first place. I was disappointed not to win last year. Through winter training, I strengthened my mindset and improved my golf skills. Thanks to that, I was able to win."
Kim Min-sun expressed disappointment over three bogeys in the first four holes, which hindered her chances for a comeback victory, leaving her satisfied with second place.
Park Hye-jun finished third with a total score of 13-under 203, while Kim Su-ji placed fourth at 12-under 204.
In this tournament, Park Min-ji, who was aiming for her 21st career win and a record fifth victory at a single KLPGA event, finished tied for 25th with a total score of 5-under 211.
