Yuzuki Eba, born August 3 in Tokyo, possesses violet hair, brown eyes, stands 155 cm tall with measurements B80/W57/H83, and has AB blood type. Following her father's remarriage, she lived with him, her stepmother, and stepsiblings but faced severe family tension, especially from her stepsister Rin's open indifference. This discord led her to move to Hiroshima for high school, residing with the Kirishima family through her father's connection. Sociable and outgoing, Yuzuki forms friendships easily yet displays naivety in serious situations, often causing misunderstandings or poor choices despite her high intelligence and academic excellence. Years before Hiroshima, she briefly met Haruto Kirishima at a summer festival as a lost child; he comforted her, leaving a lasting impression on her, though he forgot the encounter. In Hiroshima, she initially supported Haruto's feelings for classmate Nanami Kanzaki but developed her own romantic interest. After Nanami rejected Haruto, recognizing his unconscious preference for Yuzuki, they began dating. Yuzuki returned to Tokyo to reconcile with her family, accepting Haruto’s love confession just before leaving and agreeing to a long-distance relationship. Back in Tokyo, she abruptly cut contact with Haruto. She dated Kyousuke Kazama, Haruto’s terminally ill friend, after Kazama revealed his limited lifespan and desire to be with her, stemming from his past confessions to her in middle school, which she’d rejected. To avoid burdening Haruto, she ended their relationship via letter, citing a need to date someone from her past. After Kazama’s death following failed surgery, Yuzuki, consumed by guilt over his final days, told Haruto they should never meet again. Two years later, they reconnected by chance. Despite Haruto dating Asuka Mishima, Yuzuki pursued him, exchanging contacts and arranging meetings. During a Hiroshima group trip, she confessed her enduring love, leading Haruto to end things with Asuka, causing social isolation from friends. When her father discovered and opposed their relationship, Yuzuki left home to live with Haruto in Tokyo, prioritizing their bond over familial approval. Her father later reconciled with them. While cohabiting, Yuzuki supported Haruto’s culinary career while pursuing teaching. They navigated challenges, including interactions with neighbor Miyu Hoshina, who often misinterpreted situations. After Haruto’s job transfer to Kōchi forced long-distance separation, he broke up to avoid hindering Yuzuki’s Tokyo teaching career. They reunited years later under cherry blossoms when Haruto returned to Tokyo, fulfilling a promise. They married, had a son named Daiki and later another child. Yuzuki eventually joined Haruto in running his Hiroshima restaurant, Kirishima Shokudo, setting aside teaching.
