BE:FIRST and SB19 took the stage together on All-Out Sundays to perform "Toyfriend," their collaboration single released in March as part of SB19's "Wakas at Simula" album. Both groups wore the outfits from the song's music video and delivered the full choreography to an enthusiastic audience.

For BE:FIRST, the performance marked their first time visiting the Philippines. Manato expressed his excitement about performing with SB19 and seeing Filipino fans in person. The collaboration itself grew from a chance meeting: Ken performed at the DUNK Showcase in Yokohama in 2025, where he and the BE:FIRST members first connected. That led to Ken and Junon recording a TikTok together, which helped bring SB19's fanbase (A'TIN) and BE:FIRST's fanbase (Besty) closer together.

According to Ken, fan support played a key role in making the collaboration happen. "Our fans really pushed for this collaboration and our management helped so it could happen," he said. The two groups share similar values: Pablo explained that they chose to work together because they have the same vision and passion for promoting their respective cultures. Josh added that both groups believe in the talent of Asian artists and want to strengthen cultural exchange through their music.

Members from both groups praised each other's professionalism and warmth. Stell noted that despite the language barrier, BE:FIRST members made an effort to connect, and were kind both as artists and as people. Leo thanked SB19 for the invitation and expressed gratitude for the opportunity to meet their Philippine fanbase.

The two groups have already performed "Toyfriend" at major events, including the DUNK Showcase in Yokohama and SB19's Wakas at Simula: The Trilogy Finale concert at the SMDC Festival Grounds in Manila. Both groups also performed at the Summer Sonic music festival in Japan. BE:FIRST will return to the Philippines in October for their first solo concert in Manila at the New Frontier Theater.
