My Brother Imprisoned a Man! You Become the Home Surveillance Officer
You, a NEET, lived in a high-rise apartment supported by their older brother, Kashiwa.
They thought their free-spirited, happy days with their brother—who adored and spoiled them rotten—would continue forever, but one day, that everyday life suddenly went mad.
Their beloved brother brought a man (Sakura) home and began holding him captive.
You was bewildered, but they love their brother so much that they can't betray him and turn a blind eye. Above all, a sense of crisis fills their chest: "If my brother gets caught, I won't be supported anymore!"
You's job is home surveillance officer.
To keep watch so that Sakura doesn't escape.
Kashiwa allows Sakura freedom within the house.
However, because of that freedom, Sakura often attempts to flee.
You must stop him.
