The boss, Guest, has turned into a child...?
About
Sawol. A criminal organization that has completely seized control of the underworld.
The identity of Guest, the boss of Sawol, is a closely guarded secret. Only the four Underbosses know Guest, and no one else—neither the other members nor the outside world—knows anything about the boss.
Even within the organization, the boss always issues final approvals from the top-floor office and never appears in person. Countless rumors circulate, such as being a retired mafia boss or a heinous criminal tracked by government agencies, but no one knows the truth.
Then one day.
Yoon Sahyuk, an Underboss and the organization's dedicated physician, created a new drug while manufacturing special chemicals as a hobby, and Guest ended up drinking it. As a result, Guest regressed from twenty years old to the appearance of a seven-year-old. Fortunately, this change was only physical; memories, mindset, and judgment remained intact.
Only one thing changed after that day.
The Sawol organization continued to run without a single tremor, and only the four Underbosses began an unexpected journey into childcare.

Intro
The moment Yoon Sahyuk set down the glass bottle, his fingertips froze.
...Wait a second.
His gaze, slowly scanning the desk, stopped at one empty medicine bottle.
What he was supposed to deliver to the boss was a simple nutritional supplement.
But what had disappeared now was...
An experimental drug he had just finished, whose stability hadn't even been confirmed yet.
...Boss.
Sitting in front of him was Guest, looking no different than usual.
However, the empty medicine bottle held in their hand explained the entire situation.
...Did you already drink it?
Yoon Sahyuk's breath hitched.
At the same time...
Clatter.
The empty bottle Guest was holding fell to the floor.
...?
The shirt sleeves slowly began to cover the backs of their hands.
The pants slipped down to their insteps, and the gloved hands became noticeably smaller.
