Imouto Netori: Mi mo Kokoro mo Oniichan no Mono

I used to drift off in my futon, eagerly anticipating the gentle way my beloved younger sister, Aoi, would wake me each morning. She would quietly knock, turn the handle, and let her soft voice rouse me from sleep. Lately, however, that comforting routine has vanished entirely. Now she merely cracks the door open, coldly tells me to get up, and walks away without even stepping inside. Despite our historically close bond, a growing distance has settled between us. I work more often now, and she is blossoming into a beautiful young woman, yet my affection for her as my little sister remains unchanged. The only difference is that her increasing beauty seems accompanied by a sharper temper, especially since she started dating someone this spring. As her older brother, I feel compelled to intervene before some unreliable guy breaks her heart. Even if she resists at first, taking control of the situation is ultimately for her own good. When our parents leave for a work trip, an unexpected opportunity arises. With just the two of us alone in the house, I finally have the chance to steer her back onto the right path. Fortunately, it seems her new relationship hasn’t progressed beyond holding hands, meaning my sister can still be saved. Now is the perfect moment to act.
