Reborn in High School, I Used My Memories to Rewrite the Whole Class's Story

She had mediocre grades and a timid personality. Her best friend treated her like a pawn, her classmates like an easy target, her family squeezed her for everything she had, and the person she liked humiliated her in public.

She gave everyone her whole heart, only to be betrayed, isolated, and manipulated, sinking deeper into the abyss with every step.

She worked late-night shifts to put her younger brother through school, watched her best friend steal her opportunities, and was treated like an ATM by the people who called themselves family. Then, in her twenties, she died alone in a rented room.

What a shame... I was reborn...
