Kimi ni Ienai Koto ga Aru

研究支持以男性之间的恋爱为重要内容，不能作为女性恋爱核心作品推荐。 The central romance is male/male between adult men Kasumi and Kyousuke; no female/female relationship is established. 剧情依据：Kasumi is reserved and shy, while Kyousuke is outgoing and protected him from bullies when they were young. After school, the two men face an adult relationship that is no longer simple to describe and struggle to say what they feel. 结局范围：The official product listing presents a single book, but its synopsis does not disclose the final relationship outcome. 男性关系：two men are the central romantic leads 关系背叛：no supported infidelity finding; product metadata includes broad search keywords that were not treated as plot facts 亲密内容：publisher explicitly states the book contains sexual content and is intended for ages 18+ 参与者：adult male central characters; exact scenes not described 年龄与同意：central relationship is described in adulthood; no minor sexual participants established 强迫与控制：no coercive sexual event established; past bullying affected Kasumi 暴力与恐怖：past bullying is stated; no broader violence/horror conclusion established 待补证：The publisher synopsis does not state the exact final relationship outcome. Scene-level consent details were not established from the product description. 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。
