Saito can't take his eyes off Yagi's wife, Azusa's big tits, who greets them when they arrive home drunk. However, Yagi and Saito, who have been chatting for a while, get into an argument due to a difference of opinion about work. Saito, who was incompletely burned, planned to take out his frustrated feelings on Azusa.
