In a certain men's single apartment, there live three good buddies with different personalities but very congenial. They are Yokoyama Kaname (played by Yamada Takayuki), who aspires to become a director and is now working in a video store, Mano Shinhiro (played by Hayashi Kento), a genius graduate student in pharmacy with a deviation value of 72, and Nitta Hiroshige (played by Abe Shinnosuke), who works for a courier company and has a back muscle strength of up to 280 kg. Their relationship began in college, and of course it was thanks to the oldest Yokoyama who kept retaking the exam that the three of them had an intersection. After five years of training, they have become good comrades who appreciate each other and can complain about each other. They have been sharing a house for a year and a half, playing board games and making jokes in their daily lives, and colliding with people who occasionally break into their lives. Life is ordinary, but the three big boys make it fun and humane!
