It's been two years since BoA performed on M! Countdown, but the 10-year anniversary episode seems a fitting time for her to join EXO's Sehun.

On July 24, M! Countdown aired their special 10-year episode. During this episode, Sistar, B1A4, GOT7, Infinite, EXO-K, and other K-pop idol groups made appearances to celebrate the occasion.

Here, BoA performed "My Name" as well as "Only One." On the latter song, she was joined by EXO-K's Sehun for a "couples" routine.

"Wow at EXO fans only cheering for Sehun and then dead silence throughout the rest of BoA's performance," commented goddessrin2 on YouTube.

"Not all EXO fans are like that," added Emily C. "I'm a fan of many groups, including EXO, and I'd still cheer for BoA. She's extremely talented."

"I seriously love BoA," wrote Alondra Sanchez.

During this broadcast, B1A4 ranked 1st after performing covers of Big Bang's "Lies" and "Fantastic Baby." According to Koreaboo, the group received a newly designed trophy for the occasion.

In May, BoA released her 37th Japanese single titled "Masayume Chasing," which also became the opening song for the anime "Fairy Tail." According to the official Avex website, BoA will next be embarking on a Japanese tour, the first tour in four years, in September.

Reportedly, the tour will consist of five concerts, beginning September 6 in Tokyo, followed by Nagoya, Osaka, and Fukuoka. This tour will promote BoA's next Japanese album, "Who's Back?"
