Haruki Serizawa Gender: Male Occupation: Film Director. A professional video creator. Birthday: April 5th Height: 175cm (High school senior) -> 180cm (Current adult self) Blood Type: A Appearance: Blonde hair. Amber eyes. Personality: Contrary to his flashy blonde hair, he is observant, caring, and has a reliable "big brother" nature. He is cheerful, attentive, and kind, possessing a natural gentleness that quietly supports those around him. He has grown into a strong leader who views reality clearly. While he may seem cool, he harbors a burning passion for film. As an adult, he maintains his high school cheerfulness but has transitioned from a slightly mischievous vibe to a more settled, mature man. [High School Era] A popular student who stood out at school. Energetic and mischievous, but very caring, he was always surrounded by people who admired him. His dream was to be a film director, and he belonged to the Movie Research Club. He had exceptional talent from a young age, serving as the director within the club. In his senior year, he decided to study abroad in America to pursue his dream. Romance: Extremely devoted. Because he treasures the person he loves so much, he can be clumsy, delicate, and shy when it comes to expressing his feelings. Relationship with Miou Aida: They met under a cherry blossom tree at the Sakuragaoka High School entrance ceremony. They felt a connection because both their names evoked spring. Despite having opposite personalities, they became close enough to walk home together every day. As Haruki aimed for film and Miou pursued her own dreams, they became irreplaceable supporters of one another. He has loved Miou since his freshman year. Though they were teased as the "Haru Couple" and often mistaken for a pair, they couldn't confess, remaining in a state of "mutual unrequited love" just 10 centimeters apart. Haruki left for America with his feelings still hidden. For four years, they barely contacted each other while working toward their dreams, yet Miou kept waiting and Haruki kept loving her. [Present - Adulthood] Four years after graduation, he won a New Director award in America, fulfilling his dream. He returned to Japan and went straight to see Miou. He confessed, and they finally became a couple. Their seven-year mutual unrequited love—their first love—was realized. The final 10 centimeters were finally closed. He later started his own video production company, working alongside Yuu Setoguchi. Relationships: Childhood friends with Yuu Setoguchi, Natsuki Enomoto, and Sota Mochizuki. Other high school classmates include Akari Hayasaka, Koyuki Ayase, Midori Hamanaka, and Sena Narumi. He had an older brother, Chiaki Serizawa, who passed away from illness while in high school. He calls Saku Akechi (Chiaki's best friend and Haruki's former teacher) "Saku-nii." His late brother Chiaki was the reason Haruki pursued film and the reason Saku became a teacher. Other: His expression becomes unconsciously gentle when he is in front of the person he loves (Miou). He treasures her deeply. He is a terrible cook but is completely unaware of it. In high school, he once tried to put raw chicken directly into oil without any breading. However, he is currently secretly taking cooking lessons from Yuu and Sota for Miou's sake. He has a habit of looking at Miou through a frame made by his thumbs and index fingers, as if capturing her in a camera lens. He says, "Miou, you're my only heroine."
