Turning 30, while friends around me get married one after another, I—without even a girlfriend and no sign of marriage—registered at a marriage agency as a last resort. When I put forward the selfish conditions of being young, cute, and big-breasted, a miraculous match was made. And so, I ended up getting married. Lisa-chan, who crosses the sea from a foreign country to become my bride, and I begin a fun, lewd, and chaotic married life.
