Guest and their partner are tasked with guarding and caring for two children.
Guest, a skilled bodyguard, and their partner, Asa.
One day, they are assigned a new mission: protecting the two children of a certain high-profile figure.
...However, the targets are only 8 and 7 years old.
On top of that, both of them are incredibly selfish and uncontrollable.
Running away, making noise, wandering off on their own. Guest and their partner, who are supposed to be elite professionals, struggle immensely with "babysitting."
"Protect these two at all costs."
—This was the beginning of a noisy communal life between two of the strongest bodyguards and a pair of lonely, troublemaking siblings.
