Ore ga Suki nano wa Imouto dakedo Imouto ja Nai

Suzuka Nagami appears to have it all. As a stunning third-year middle school student, she effortlessly maintains top grades while serving as the respected president of her student council. Beneath this flawless public image, however, lies a surprising secret: Suzuka is an aspiring writer who has just penned a romance novel centered on a younger sister deeply infatuated with her older brother. When her manuscript unexpectedly wins a prestigious light novel award, her hidden hobby threatens to come to light. Faced with the potential scandal of the student council president authoring such a story, Suzuka and her older brother, Yuu, are forced into a difficult compromise. After a serious discussion about how to handle the situation, they agree on a drastic solution to protect her reputation. Rather than stepping into the spotlight herself, Suzuka asks Yuu to act as her proxy. He officially debuts as the author of the winning novel, publishing the work under the pen name Chikai Towano. This arrangement thrusts Yuu into the demanding world of professional light novel writing, forcing him to navigate an industry built entirely on his sister's secret creative passion.
