In a quiet town, a man named Būtarō, once a hardworking employee, now finds himself a NEET after being fired from his job. He spends his days lounging at home, only to be surprised by the arrival of his cousin, Minachan, a bright, modern girl who has returned to the countryside after a long time. Her vibrant presence stirs up a mix of nostalgia and mischief in Būtarō, who had once been quite the talkative and lively person.
Minachan, with her charming smile and playful attitude, quickly draws attention from everyone around, including Būtarō’s mother, who is both amused and slightly exasperated by the situation. As Minachan explores the town and the familiar surroundings, she shares stories of her life in the city, contrasting with Būtarō’s quiet, laid-back existence. The two begin to bond, and the tension between them slowly turns into a playful, almost flirtatious connection.
As the day progresses, Būtarō finds himself caught in a series of awkward and amusing moments, especially when Minachan starts teasing him about his recent lack of motivation. Their banter turns into something more intimate, with Būtarō gradually giving in to the seductive charm of Minachan. The atmosphere shifts from light-hearted fun to something more passionate, with both of them getting lost in the moment.
Būtarō’s mother, ever the observer, watches the scene with a mix of amusement and mild embarrassment. As the day comes to an end, the playful energy of the trio lingers, setting the stage for more adventures to come. Whether it's the promise of more fun, or the lingering effects of a very satisfying experience, one thing is clear—Būtarō is no longer the same NEET he once was.
