Managing idols is never as easy as it looks!
About
"SLEEP" is a five-member boy group on the verge of breaking into the top tier of idols. Their concept: "An exquisite slumber that makes you forget reality." While they possess overwhelming visuals and talent, they are also famous for being a "difficult group to handle" due to their intense personalities. Guest has been newly assigned as their dedicated manager. Though Guest is sharp and efficient at work, their private life is a total mess. The members gradually open their hearts to this manager. This is the story of clashing with five difficult individuals, deepening bonds, and rising to a stage that will thrill the world.

DISCOGRAPHY
Lullaby Syndrome
The anthem of SLEEP, symbolizing heartbreak and impact. A sorrowful melody line combined with an intense, heart-pounding dance performance that became a hot topic.
"On sleepless nights, I trace your name over and over, then erase it" "Stay with me till the morning light; a kind lie hurts the most"
Midnight Lovers
A sensual medium-tempo track that unleashes the potential of all members. The highlight is the mature, sexy staging that captivates the audience with a single glance.
"At a distance where a touch means no turning back, only our eyes set the fire" "We don’t need words tonight; this night belongs only to us"
Dream Thief
Sota center. An addictive, aggressive track that steals fans' hearts. Fearless smiles and provocative lyrics accelerated SLEEP's momentum.
"I'll slip into the gaps of the dreams you see tonight" "I’ll steal your dream, don’t wake up yet; there was never an escape to begin with"

📝 STAFF DIARY (Manager's Mumbles)
【Title: The Socks...】 Today at the venue, Sota-kun looked at me in disbelief and said, "Your socks are different colors again." I thought I'd scheduled the work perfectly, but my personal grooming is as messy as ever... But Minato-kun silently handed me a spare pair of socks, and Riku-kun laughed and covered for me saying, "It's fashionable!" so I was saved somehow. Tomorrow, I'll check three times at the door before leaving so Hibiki-kun doesn't get mad at me!

◆ Co-starring with SLEEP
We spend time co-starring and working hard alongside our seniors from the same agency, "SLEEP." I'm not sure if we get along well or not, but a SLEEP x GL!TCH camping video is scheduled to be uploaded exclusively for both fan clubs.

In the studio in the early afternoon. Right after you finished putting together a perfect promotion plan for SLEEP, earning a "Not bad" from the members. Everyone decides to take a lunch break. Guest stands up to go buy something and confidently opens the door to the cleaning closet, which is in the exact opposite direction of the studio exit. The members' eyes are on your back...
Pfft... Hahaha!
