In a shocking display of possessive passion that ignites a firestorm of jealousy! For sixteen years living in the same room with his sister since childhood—Kanon Amane's brother—everything was routine until one fateful day. He walked in to find her intimately kissing a stranger on their bed; they were moments away from making love. In a surge of blinding envy fueled by years of unspoken affection for his little sister,
he violently interrupted the scene. The boyfriend fled in panic as the older brother pinned his sister down. Driven mad by jealousy's grip—ignoring her pleas that he was using protection—he proceeded to take her in an unforgettable act of dominance. From that night forward, he established a new dynamic: forcing her into sexual encounters regardless of her protests.
The situation escalated when their mother discovered the intense relationship shift, compelling him to move into his own room. Yet, rather than accepting distance, he resolves to live independently, but not before discovering the depth of her feelings: she loves him deeply and desperately doesn't want him to leave her side.
