OVA
Description
Kyōko Hori is a popular and academically successful high school student, projecting social adeptness, yet privately shoulders significant domestic responsibilities, caring for her younger brother Souta due to her parents' frequent absences. This hidden life remains concealed until classmate Izumi Miyamura helps Souta, accidentally discovering her reality. This leads to a pact of mutual secrecy regarding their hidden identities, forming the basis of their connection.

Physically, Hori has chestnut-colored wavy hair reaching her mid-back, styled with bangs swept right and two chin-length strands framing her face. Her appearance shifts contextually: at school, she wears seasonal uniforms, light makeup, and her hair down; at home, she forgoes makeup, favors practical clothes like t-shirts and jeans, and often ties her hair in ponytails or buns. She stands 163 cm (5'4") tall, with fair skin, golden brown eyes, a slender athletic build, and a double-jointed right index finger.

Hori blends diligence with volatility. She excels academically, consistently scoring above 90%, and manages her household competently. However, she reacts aggressively when embarrassed or flustered, often hitting people with objects, an intensity others find intimidating during activities like ear cleaning. She exhibits masochistic inclinations, deriving gratification when Miyamura adopts a "bad boy" persona, requesting he shout at or physically discipline her despite his reluctance, feeling refreshed afterward. Intense jealousy emerges when Miyamura gains popularity, earning her the "Hannya" (Goddess of Jealousy) nickname. She feels particularly threatened by his deep connections with male friends, fearing she cannot compete.

Her relationship with Miyamura evolves from mutual secrecy to romance. She gradually develops feelings, acknowledges him as her boyfriend to her father, and they eventually marry—she takes the surname Miyamura—and have a son, Kyouhei. Their bond deepens despite challenges like her separation anxiety and reliance on him, or conflicts such as disagreements over his uncharged phone.

Her family includes father Kyousuke, mother Yuriko, and brother Souta. She is the youngest in her grade, allergic to blueberries, dislikes stew and grapefruit-flavored foods (though eats mikan), struggles with tongue twisters, enjoys horror movies, and favors the anime *Riho's World*. Past childhood baths with family friend Kakeru Sengoku ceased during adolescence. Her zodiac sign is Aries.
