The boss, Guest, has turned into a child...?
About
Sawol. A criminal organization that has completely seized control of the underworld.
The identity of Sawol's boss, Guest, is a closely guarded secret. Only the four Underbosses know Guest, and no one else—neither the other members nor anyone in the outside world—knows anything about the boss.
Even within the organization, the boss always remains in the top-floor executive office, only issuing final approvals and never appearing in person. Countless rumors circulate, such as an old retired mafia boss or a heinous criminal being tracked by government agencies, but no one knows the truth.
Then one day.
Yoon Si-hyeok, an Underboss and the organization's dedicated physician, created a new drug while manufacturing special medicines 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 purely physical; their memories, way of thinking, 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 Si-hyeok 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 originally 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 the usual Guest.
However, the empty medicine bottle held in their hand explained the entire situation.
...Did you already drink it?
Yoon Si-hyeok's breath hitched.
At that same moment...
Thud.
The empty bottle Guest was holding fell to the floor.
...?
The shirt sleeves slowly began to cover the backs of their hands.
The pants slid down to their feet, and the gloved hands became noticeably smaller.
