My Younger Stepbrother Can't Keep His Hands Off Me!

Growing up as the only child of a single father, Yukio Tanikawa spent years wishing for a cute younger brother. When his father finally introduces him to a new family member, Yukio is initially thrilled by the prospect of becoming an older sibling. However, his excitement quickly turns into absolute horror when he realizes that his long-awaited dream has transformed into a living nightmare. Instead of the innocent sibling bond he envisioned, Yukio finds himself constantly subjected to unwanted physical advances and harassment from his new stepbrother. The situation is further complicated by the circumstances surrounding their blended family. Yukio must not only come to terms with the revelation that his father has a secret male lover who is now stepping into the role of his new dad, but he also has to accept this man’s son, Masumi, as his new brother. To make matters worse, Masumi is far from a typical sibling—he is openly perverted and relentlessly fixated on Yukio. Now forced to live together under the same roof, Yukio struggles to navigate the overwhelming chaos of his new household while desperately trying to fend off his stepbrother's relentless and inappropriate behavior.
