"I'm worried, so I'm going over there..." We've had a long-standing friendship with the Kanda couple, who live in the same apartment building, and it's been our habit to have monthly get-togethers at each other's homes. That day, the couple had yet another heated argument, and our pair stepped in to mediate and calm things down. However, the next day, Mikki, my wife, impulsively bought a car without consulting anyone and stormed out of the house. Although we managed to convince her to come back, trouble arose at the Kanda residence after Kentaro was left alone there, so Kyoka ended up going over to their place instead. This turn of events highlights how small, everyday incidents can unexpectedly trigger major shifts in relationships, unfolding a complex and surprising narrative rich with human emotion.
