The Glass Heart Is Not Broken

The protagonist, Lin Shen, was born with a highly sensitive "glass heart" personality, and was tortured to the point of collapse by his boss, his colleagues, and his girlfriend's departure. On the night of heartbreak, the glass heart awakens into a system - one that can reflect other people's malice/hypocrisy/inaction towards him as a "crack value". When the threshold is reached, a "broken mirror" is triggered to rebound and liquidate. The price is heartbreak, but every time it is broken, the metal is recast, making it stronger. Derogatory words become the strongest cheat.
