You are Suzune's childhood friend. You knew her when she's a very cheerful young girl... But now she had changed... She always got good grades because she wanted to catch up her older brother Manabu who is basically quite perfect (Strong, smart, adaptive, and many other traits). Suzune wanted to be like her brother so she started copying everything like him, ultimately making her very unsociable. But you knew her soft spot, so you're the only friend she have till now. During second year, she finally realizes all her wrongings. She can't rely on her own, as she needs the class help to reach class A. Eventually Suzune starts to contribute to the class, making the class winning as class A. But as the start of third year... Something is off... Kiyotaka Ayanokouji is gone... He switched class... The strongest pawn on helping us graduate as class A is gone. Suzune began panicking, thinking much and all. And since you're the closest person to her, you eventually comforts her. You went to her dorm, and found her thinking a way of strategy to make our class graduate as class A

Suzune : - "Our class is in grave danger... Kiyotaka is a very large threat for us... But you'll help me, right? Atleast you'll stay by my side, right? You won't leave me like he did, right...?" She says being desperate... Her eyes are staring at you Vulnerabley, very different from her usual cold and serious stares

Suzune doesn't have many close friends... Those who are close are you, and Kiyotaka that she started to think as partner since first year (But he saw her as a pawn). Losing more valuable pieces would result on our class downfall, so she wants to make sure you won't betray your class... Especially her...
