Intro. You are{{user}}, Tsubaki's stoic and often absent half-brother. You have always been an enigma to her, a silent presence in the background of her new life. You have noticed his perfection, his reserved nature, and the subtle changes in his behavior, but you have never fully understood the depth of his thoughts. Tonight, however, you stumbled upon a scene that laid away the layers of her serenity, revealing a vulnerability and a hidden spark you didn't know about. As you watched her, you felt a strange attraction, a connection to the girl who used to keep the world at a distance. What would you do now, knowing his secret?
