👑 The Truth Behind the Retirement of the "Legendary Idol☆"
Once, there was a legendary solo idol who made their name known all over the world: Guest. However, four years ago, at the height of their popularity, they suddenly retired and—
Vanished from the entertainment industry.
While various speculations are flying around in public,
Almost no one knows the truth.
Some might be curious about the reason for retirement. I won't te— actually, I'll just tell you. The reason for retirement was that they suddenly turned into a toddler!!! Why? Don't ask me!!
Not just in appearance... Guest's physical structure became that of a toddler, making it impossible to continue idol activities, and they were forced to retire.
🧸 Exclusive Caretakers
The toddlerfied Guest had exclusive caretakers. They were there to support all aspects of life, including meals, changing clothes, bathing, sleeping, and accompanying them on outings.
...However, the previous caretakers were all problem cases.
Caretaker #1: A sexual harasser who touched Guest against their will. Caretaker #2: A delusional guy who thought he could date Guest once they returned to normal. Caretaker #3: A lazy guy who only wanted money and barely did any housework. Caretaker #4: Someone who could do the job but was a stalker who bugged the house and took secret photos. Naturally, they were all fired. They deserved it; they were out of their minds.
After a series of such replacements, Guest finally met a sincere and perfect caretaker.
Now a peaceful life will return...
Just when things seemed fine,
that person had to leave Guest's side due to personal circumstances.
And so, the ones chosen as the new caretakers were— eight male idols.
👑 The Agency's Intentions (Bonus)
The agency knows as a matter of course that all eight are huge fans of the legendary idol Guest. Furthermore, based on their usual work ethic and character, the agency deemed them sincere enough to be entrusted with the precious Guest.
One person might be worrying, but eight should be fine. Based on that bold judgment, they decided to request the whole group to handle the caretaking.
...However, the agency had another motive.
"I wonder how those guys will react when they find out the toddler in front of them is that legendary Guest?"
Yes, it was pure, simple curiosity.
Based on the failures of previous caretakers, Guest's identity is a secret this time. For some reason, Umi has noticed the truth, but the other eight know nothing.
So,
without dreaming that this is their idol,
as they take care of a toddler...
What will become of these eight—!?
Since there are eight of them and they have their own idol activities, they take turns looking after Guest.
▶ Guest's Settings
A former solo idol whose popularity eventually spread worldwide, a global Idol☆. Currently missing... Or so it seemed, but the reason for retirement was toddlerfication, and life is difficult without a caretaker. Has a good face. Since it's been four years since retirement, the physical age is at least 4 years old. Reason they don't find out: Guest is not recognized because they have a stage name and a real name. (Actually a prank / streaming in toddler form... etc.)
Any reason for toddlerfication is fine. Examples: Lost memories and became small. Only the mental age became child-like. Has memories but cannot resist the child's body or instincts.
Gender, age, height, and everything else is free!!
