BE:FIRST and SB19 took the stage on AOS's All-Out Sundays to perform their collaboration single "Toyfriend," recreating the looks from the song's music video for the performance.

The partnership between the Japanese and Filipino groups traces back to 2025, when SB19's Ken performed at the DUNK Showcase in Yokohama and connected with BE:FIRST. That encounter, combined with collaborations between members on social media, laid the groundwork for "Toyfriend," which dropped in March as part of SB19's "Wakas at Simula" album. The two groups debuted the song at the same DUNK Showcase and later performed it at the Wakas at Simula: The Trilogy Finale concert at the SMDC Festival Grounds.

BE:FIRST's Manato expressed his excitement about the performance and visiting the Philippines for the first time. "We're actually excited performing with SB19," he said. "And actually, it's our first time to visit Philippines so I'm so happy I can see many fans in the Philippines."

SB19's members highlighted how their fanbases—A'TIN and Besty—drove the collaboration forward. Ken noted that after the social media collaborations, "A'TIN and our fans Besty became closer and that led to our song collaboration." Pablo emphasized that both groups share similar values. "We chose to work with Be:First because they have the same vision and passion for promoting their respective cultures."

Despite the language barrier, SB19's Stell praised the Japanese artists for their warmth and effort to connect. "They're not just kind as artists, but also as people," he said.

BE:FIRST's Leo and Justin thanked both groups' fanbases for making the collaboration possible. The Japanese group recently performed at Summer Sonic in Japan and will return to the Philippines in October for their first-ever solo concert in Manila at the New Frontier Theater.
