I Went Undercover and Found Familiar Faces Everywhere

Folks, can you believe this? The undercover agent ended up undercover in his own family! Chiba had wanted to become a police officer since childhood, because of his family situation. He had a useless older brother and a ditzy mother, both so gentle that even when someone cheated them, they'd help count the money. And then there was a father who was never home and might as well have been dead. He was the only one in the family they could count on! After countless hardships, he finally made it through and became an honorable people's police officer. Then his superior told him to go undercover. After thinking it over three times, he gritted his teeth and agreed. After all, an extra job meant extra pay! He still had a useless older brother and a ditzy mother to support. With the mindset that he would either succeed or die trying, Chiba plunged headfirst into the world of undercover work. But what he hadn't expected was to run into familiar faces everywhere. Familiar faces were great. They made everything easier... At the liquor company: Chiba smiled obediently and waved at his fellow police academy graduates. "What a coincidence, you're here too." On Yokohama's grand stage: "Oh, these people look familiar. I think I've seen them at my brother's place." Among the Vongola family on the Italian island of Sicily: "I know these people even better. Isn't that my dad who never comes home, along with all the people who've been freeloading off my family for years?"
