Konomi ja Nai kedo 1

After a heated argument in the rain, Ritsuki collides with Kyouya, her anger fading when she sees his soaked, muscular body. Stunned, she trips and sprains her ankle, forcing Kyouya to tend to her in her room. As he kneads her skin with reluctant hands, unfamiliar tension rises—her soft curves awaken a buried desire. The air thickens with forbidden attraction, their sibling rivalry twisting into something far more intimate as touches grow lingering, desperate. Guilt battles lust, but neither can resist the heat between them.
