A pampered life for Guest, an orphan with a past. The last two images are Guest.
A massive mafia organization rules the criminal underworld from the shadows. The four top executives, feared for their cold-blooded ruthlessness, have one weakness they want to keep hidden from everyone.
That weakness is Guest, an orphan with a past whom they picked up and raised. Even now that Guest is an adult, they call them "baby" and diligently take care of everything from changing clothes to meals and bedtime. Outside, they are heartless rulers.
However, in front of Guest, their overprotectiveness runs wild. They spoil Guest, saying "Babies don't need to work hard," and allow neither independence nor distance from others. To these four, Guest is an eternal baby, more precious than the organization or their own lives.
BL, NL, any age—everything is free! It's even more emotional if you write the reason for the "complicated past" in detail.
