Saichi Nagase is a habitual liar, and is also Tosaka Real Estate’s number one salesman. Sakura Tsukishita, the newest employee, firmly believes in the mantra, “customer first.” One day, Nagase is cursed with the inability to tell a lie. He's angering all of his clients by blurting out the cold, hard truth. Meanwhile, Tsukishita is charged with finding a rental property for her first client.

Nagase can no longer tell a lie, and he is no longer top dog in sales. Now, Kiriyama's in first place. As the two fight internally over clients, Tsukishita struggles to generate any business at all with her mantra, “customer first.” One day, Kiriyama kindly offers up one of his clients to Nagase. Nagase jumps at the chance, only to discover that there is a problem with the property.

Nagase sold a property to a couple under a pair loan agreement, but now they're back with divorce papers in hand, complaining about the loan repayments. Tsukishita is charged with finding her first commercial tenant, and finds an elderly couple who cannot afford the rent. She decides to go directly to the property’s owner to ask for a rent reduction. However, this is no regular landlord.

Tosaka Real Estate and Minerva Real Estate, two rival agencies, compete to see who can sell a property first. Nagase is eager to come out on top and earn some extra money, while Ryoko Hanasawa, a realtor at Minerva, declares an all-out war. Meanwhile, an eccentric older lady is in the market for a haunted house, so Tsukishita decides to help her find a so-called, “stigmatized property.”

Tosaka Real Estate is losing business, and Nagase suspects a spy is in their ranks. Meanwhile, Tsukishita’s father suddenly appears after disappearing for eight years following her parents’ divorce. When Tsukishita learns that her father is moving to Tokyo for work, she offers to find him a new place. However, he ends up being coerced into a suspicious deal by Minerva.

Tosaka is suspected of being a spy, but Nagase is in disbelief. The two are asked to handle a large business deal together. Tasked with selling house and land packages en masse, the two discover that all of the decisions have been left up to a cheap contractor. Judging from the amount being spent, it is clear that the properties will be defective.

The spy within Tosaka Real Estate was all Minerva’s doing. With the company down a manager, Nagase is promoted to acting manager. Not only is he swamped in paperwork, but many of his former clients are now raising complaints about his past conduct. Minami Enomoto has a client looking to sell a property, so she comes to Nagase seeking his assistance.

Nagase and Tsukishita are entrusted with a huge land sale worth 500 million yen. With so few sales as of late, the two are desperate to ensure this deal is a success. However, the landowners seem to be acting strangely, and Nagase cannot shake the feeling that something is amiss. In his desperation, Nagase reaches out to a former coworker.

Tosaka Real Estate’s performance is going down, while Minerva Real Estate’s is only going up. The two presidents, Mr. Tosaka and Mr. Ikaruga appear to have a hostile relationship that goes back decades. Nagase finds himself caught in the middle of the resulting maelstrom, while Tsukishita competes against Hanasawa to find the perfect property that has a view of Mt. Fuji.

Minerva Real Estate is plotting to snatch all of Tosaka Real Estate’s properties from under their noses, in an attempt to crush the company entirely. A high-value property is about to change hands, and Minerva offers the owner a lucrative sub-leasing contract. With his company staring down the barrel, Nagase desperately prays to the gods to grant him the power to lie again.
