Gorou Natsume

This dedicated physician is responsible for caring for Rika, having relocated from another facility to Yūichi's town. Despite his professional role, he secretly harbors feelings for Rika and actively attempts to disrupt her and Yūichi's romance, viewing it as a playful endeavor. His actions stem from personal grief, as he experienced a similar loss with his wife, fueling a deep, protective desire to prevent Yūichi from suffering a similar fate.
