MONSTA X's Kihyun is back with solo music. On July 7 at 6 p.m. KST, the vocalist released his second mini album "BORDERLINE" along with the accompanying music video for title track "So Good."

The new single captures a theme of freedom and self-empowerment. "So Good" explores the liberation that comes when you trust your own judgment and instincts—a personal journey Kihyun channels into the track's sound and visuals. The music video reinforces this message of independence and confidence, giving fans a clear look at the creative direction for this comeback.

This release represents an exciting moment for Kihyun's solo career. While details about the full "BORDERLINE" tracklist and other album standouts aren't yet available, the emphasis on self-determination and trusting oneself suggests the mini album may carry similar themes throughout.

Kihyun has been a cornerstone of MONSTA X since the group's debut in 2015, known for his powerful vocals and stage presence. His solo work allows him to explore different artistic territory while the group continues its own projects. Fans have been anticipating his return, and "So Good" gives them plenty to look forward to.

The July 7 release keeps things moving for MONSTA X's members as they balance group activities with individual endeavors. With "So Good" now out in the world, Kihyun's second solo chapter is officially underway.
