Themes of contemporary family and marriage provide plenty of laughs and inspiration in this domestic drama about a 39-year-old bachelor who can’t marry and a 32-year-old female divorcee who refuses to. Both would prefer to be left alone, but their meddlesome parents won’t let them. Daisuke works at a stationary supply company, and is something of a softie, but with a pessimistic view toward marriage. He returns from work one day looking for rest and repose in his recently purchased condo only to find it billowing smoke. Panicking, he runs into a woman in the apartment of a neighbor, Hanako, until he realizes that his apartment isn’t on fire, but that his father has come uninvited from the countryside and is trying to smoke meat on the balcony. What’s more, he’s brought his stepson with him and plans to stick around. Soon, Daisuke’s comfortable bachelor pad is populated by three men.

The Metropolitan Police Agency's most eccentric detective, Heihachi Hiratsuka, of the First Criminal Investigation Division is the sole member of the “Hiratsuka Unit.” Treated as a pariah by his colleagues, Hiratsuka nevertheless is a stellar detective who cracks one mystery after another, thereby leading other division members to suspect his activities and speculate that he has deep ties to the underworld. When he is assigned a new partner in the form of rookie detective Saionji, an extravagant celebrity type with a strong sense of justice, there is the hope that he will discover evidence of Hiratsuka’s purported corruption. But the primary reason for Hiratsuka’s success in solving criminal cases may lie merely in the fact that the bad guys loathe him as much as the good guys do. The eccentric P.I and his rookie “frat boy” partner form an odd couple in this fun and quirky mystery drama.
