After meeting Rina, Yamato stopped having sex with her, yet he continued to maintain his role as her advisor. He always remained passionate about sex, valuing the importance of staying true to his own sexual philosophy. Though he never developed the desire to build a committed relationship with a "girlfriend," he never ceased enjoying new partners. One day, a woman he had sex with for the first time asked him, "Do you actually hate sex?" Her words made Yamato deeply reflect.
