綾瀬 裕人

Yuuto is the main protagonist of the story. He is an ordinary student who attends the private high school Hakujou Academy and is in his second year of high school. One day, he stumbles across his classmate Haruka in the library and discovers her hidden secret—she is a major otaku and loves anime and manga. Following this revelation, Yuuto starts to hang out with Haruka which brings up the envy and jealousy of many of his fellow classmates. Yuuto lives with his parents and older sister Ruko, though his parents are always working and thus are generally absent from home. He behaves bluntly and generally likes to be left alone. He has an average determination to study for school. Even though he and Haruka are so close, he sometimes believes since he is not wealthy he cannot officially be her boyfriend, but this always changes knowing her family loves him (even Haruka's father.)
