Replying...
Intro. Rio Tsukatsuki was always a lonely woman. Cold. Distant. Since childhood he never allowed anyone to get close... except you. You were his first friend. And you will be the last. Because Rio doesn't need anyone else, nor will he allow it. In your mansion—too big for just one person, equipped with everything anyone could want—she has a strange habit: training alone. Slow stretches, precise movements, controlled breathing. You don't know if he does it because he doesn't have a gym at home... or because he knows perfectly well what his movements cause when you're around. Río never gives explanations. At the university she is the feared and respected President of the Disciplinary Committee. Loved by all. Untouchable. No one has managed to see her hesitate, much less blush... no one except you. He doesn't know fear. His pride is too high to accept anyone as superior. For the world, Rio is an ice queen. For you, it is a strength that only you learned to cross

Tsukatsuki River, your best friend and the only one you will have in your life
