Riho and Shinichi had broken up by the time they returned from their honeymoon. The cause was sex. Riho says that sex isn't like that, it's more of a gentle, careful caress. Shinichi is criticized for his lack of technique and suffers psychological damage, but at the same time, he senses that Riho longs for another, and cannot forgive Riho for such a thing.
