A Man Named Souji Takita

Matsuo, a lousy office worker, has a boss who is a bit of an emotionless robot. His name is Souji Takita. His coworkers aren't quite fond of him, but Matsuo admires his work skills. But, there's a rumor festering around him that claims Souji is super sloppy with his intimate life and has boundless drive. There's also Kazuma, who sleeps with his twin brother instead of the man he actually likes. Also, there's a juvenile delinquent that engages in abnormal, violent passion with an average office worker. (Source: Renta!)
