The Story of Our Marriage

The lively Sato Sachi and the earnest Sato Tamotsu. Though complete opposites in personality, the two met in college, hit it off, and began living together.
Five years later, Tamotsu, aiming to become a lawyer, fails the bar exam. To support him as he continues studying on his own, Sachi decides to study as well and take the exam alongside him. And the one who passes with flying colors is… Sachi.
Now, Sachi works as a lawyer, while Tamotsu continues studying while also handling childcare and housework. They should be the same two people they were back then. And yet… why is it that things are gradually changing?
