Kare to Kanojo no Sentaku

研究正文明确给出占据主线的男性恋爱对象、异性恋主线或男性中心后宫结构。 The central developing relationship is current female Haruka/male Kazuma, with female Aika also interested in Kazuma. This is a fantasy bodily sex-change and heterosexual/mixed triangle structure, not native female/female GL and not evidence of a transgender identity narrative. 剧情依据：Kazuma reunites with childhood friend Haruka, who previously lived as male and now has a female body because of the fictional 'sex differentiation change disease.' They live together while friendship changes toward romance, and female Aika's feelings for Kazuma create additional relationship pressure. 结局范围：The series is complete at five volumes. KADOKAWA's final-volume synopsis confirms Haruka recognizes feelings for Kazuma and the volume reaches the pair's choice, but no marriage, children, or more specific epilogue is added beyond the official copy. 男性关系：male Kazuma is the central love interest and cohabiting counterpart 关系背叛：a love triangle is confirmed, but cheating or partner theft is not established 亲密内容：not established by cited official summaries 参与者：young-adult or late-adolescent cast; exact ages not verified 年龄与同意：cohabitation and bodily transformation require direct scene review; no specific coercive sexual act is established 强迫与控制：medical/social pressure around bodily change may exist; relationship coercion is not established by cited summaries 暴力与恐怖：not central in cited material 待补证：Direct-volume review is still needed for exact final wording, sexual-content level, and scene-level consent. 基于既有研究资料作出的 AI 评级；未重新抓取外部资料。未知项不表示安全或不存在。
