He encounters and follows a beautiful girl who saves him, confessing his love for her at a bus stop. The girl, Tsukasa Tsukuyomi, agrees to become his girlfriend, but only if they are married first. When Nasa, who had previously decided to not go to high school in order to look for Tsukasa, reaches his 18th birthday, he is still thinking about the promise he made on that day. Suddenly, Tsukasa shows up at his doorstep with a marriage form, starting their relationship and their marriage. Their newlywed life begins as they encounter comedic romance issues while dealing with characters debating or against their relationship.
