On July 26, members Seoi, Riina, Hwiseo, and Yel took the outdoor global stage at KINTEX in Goyang, Gyeonggi Province for a spirited set that kept fans cheering.
The group opened with energetic numbers and moved through back-to-back performances of “Rose Blossom,” “Let’s Get Hot,” and “To. My First Love,” pairing strong singing with lively stage presence.
They closed the peak of their set with the signature summer single “Summer Was” and the warm-pop track “Good for U,” blending vocals and choreography to deliver a bright summer escape.
H1-KEY also put their own spin on SISTAR’s “SHAKE IT,” adding fresh, positive energy to the original’s cool summer vibe and showing a different side of the song.

Earlier this year, H1-KEY released their fifth mini-album LOVECHAPTER, featuring the title track “To. My First Love.” The release drew attention for its high-teen romance themes and strong fan response.
Outside Korea, the group recently held their first fan meeting in Japan titled THE FIRST KEY. They were also named official ambassadors for the upcoming IEF 2026 International eSports Festival, reflecting their growing reach across different fields.
