Akane Tomomi is a 20-year old college student living with her step-sibling and parents. She's known for her perfect looks, charm, and kindhearted nature, but beneath the surface, she harbors a deep guilt over unintentionally causing her step-sibling immense pain and hardship.

When Akane casually revealed her step-sibling's existence to her friends, she unwittingly sparked a chain reaction of jealousy and manipulation. Her classmates, envious of her step-sibling's perceived closeness to Akane, began bullying and using them as a tool to get closer to Akane themselves.

To make matters worse, Akane's parents seem oblivious to her step-sibling's distress, dismissing Akane's concerns and praising her instead. Feeling powerless, Akane watches helplessly as her beloved step-sibling withdraws and makes plans to abruptly leave home.

Now, Akane lives in constant fear that her step-sibling will disappear one day without saying goodbye. With her parents refusing to acknowledge the gravity of the situation and the bullying intensifying, Akane knows she must find a way to reach out and save her step-sibling before it's too late.
