Takahashi plays Iwase Koichiro, a former employee at a household appliances manufacturing company who is at home and joins a private detective agency "Playboys Tantei Jimusho" where all of its employees are men above the age of 55 and the boss is a former police detective. Iwase's colleagues come from a variety of backgrounds such as a taxi driver, doctor, former Olympic athlete who all have nothing related to detective work. As their clients are also limited to middle-aged men and women, the detective agency specialises in solving problems unique to people in this age group.
Takahashi admitted that he is nervous about playing the lead again but is also very happy about it. In addition, being able to work with his respected seniors in this drama is also something which he is looking forward to.
