The father of the protagonist in the anime and manga Love My Life is named Housei Izumiya. He is a professional translator, working from home to translate English novels into Japanese, which is the same career path his daughter, Ichiko, has chosen to pursue. He is a widower, as his wife passed away seven years before the story begins.

Housei Izumiya presents the calm and steady presence of a caring single parent. His personality is defined by his quiet honesty and an open-minded acceptance that challenges conventional expectations. When his daughter introduces her girlfriend, Eri, and comes out to him, his reaction is not one of shock or disapproval. Instead, he remains composed and responds with a revelation of his own, demonstrating a thoughtful and deeply sincere nature.

His primary motivation seems to have been the creation of a stable and loving family. He entered into a marriage of convenience with his late wife, fully aware that she was a lesbian. Their agreement was to marry in name only to provide a supportive home for a child they would raise together, all while maintaining their own separate romantic relationships with other people. This arrangement was driven by a mutual desire for parenthood within the social constraints of Japan.

In the story, Housei Izumiya plays a crucial role as the catalyst for the central twist that shapes Ichiko's understanding of her family. Rather than being an obstacle to her identity, he is a source of unexpected solidarity. His revelation that both he and her mother were gay reframes Ichiko's perception of her own childhood and her parents' marriage, turning a potentially difficult coming-out moment into a shared experience of understanding.

His most significant relationship is with his daughter, Ichiko. Their bond is portrayed as warm and respectful, allowing for an honest conversation about their identities. He also has a romantic partner, a boyfriend whom Ichiko eventually meets, showing the ongoing fulfillment of the life he and his late wife agreed upon. His relationship with his deceased wife is complex; while not a romantic one, it was a partnership based on deep friendship and shared goals, demonstrating a non-traditional but functional family unit.

Housei Izumiya does not undergo a dramatic personal transformation throughout the narrative. His development is instead revealed through the context he provides for the past. The story does not show him changing who he is, but rather fully explaining the honest and unconventional life he has already been living. This revelation helps his daughter accept her own life and relationships more freely.
