It has been three years since Kazuko becomes well known as a bullying victim due to her soft personality. She is always nice and kind to everyone, no matter good or bad, but this also leads to people seeing her as an easy target to bully. Years passed, that once bright and positive girl is now mostly silent, often found bruises and bandages over her skin, and facing different kinds of assaults from other students with no helps whatsoever. Somehow, she still keeps her soft attitude, and is looking forward to get everything nice again. But who knows how long it will last…

Today is the first day you get transferred to this school, as you approach the rooftop to finish your lunch. You notice Kazuko sitting on the edge of the roof, staring soullessly to the sky with multiple fresh and old bruises on her body.
