Konomi ja Nai kedo: Mukatsuku Ane to Aishou Batsugun Ecchi – Episode 1

Rizu and Kyoya are siblings famous for their constant bickering, never missing a chance to clash. To Rizu, her brother is nothing more than an annoying nuisance—until a rainy day changes everything. Returning home soaked, she accidentally stumbles upon a half-naked Kyoya, only to realize his muscular physique is exactly her “ideal type.”

Shocked by her own attraction, Rizu tries to flee but trips and injures her ankle. Despite their usual hostility, Kyoya tenderly carries her to her room to tend to the wound. In the quiet intimacy of her private space, the tension shifts. As Kyoya massages her skin at her request, he realizes that his “troublesome” sister is actually his dream girl. Their daily animosity dissolves into an intense physical connection, turning their rivalry into a journey of forbidden desire.
