THE BOYZ are ready to paint summer nights with youth and emotion.

🌙 Late-night nostalgia in their new MV teaser

On July 7, IST Entertainment shared the music video teaser for THE BOYZ's upcoming 10th mini album a;effect.

In the teaser, the members ride bikes through a dimly lit parking lot, playfully teasing each other in the rain. The whole scene is soaked in pure youth energy — raw, real, and radiant.

🎵 Their first comeback in 4 months — now as a 10-member team

This album marks their first release since PHANTASY Pt.2: Sixth Sense, and their first as a 10-member group following Ju Haknyeon's departure last month. Despite the lineup change, THE BOYZ seem more united than ever.

🔥 THE BOYZ's rising power

Their last album Unexpected proved their fan power, selling over 740,000 copies in its first week — making it their 4th consecutive half-million seller.

🌍 Kicking off their world tour next month

THE BOYZ will open their 4th world tour THE BLAZE with three nights at Seoul's KSPO Dome from August 8–10.

📅 Comeback countdown: July 28, 6PM KST

Get ready — a;effect drops on all major streaming platforms, bringing the sound of summer and stories of youth.
