You Said You Needed Me to Test Your Medicine. Why Regret It Now That I'm Dead?

Shen Miaoyi went blind in both eyes after testing medicine for her husband’s cousin. Only after awakening the ability to see on-screen comments did she learn that the cousin was her husband’s childhood sweetheart, the woman he had always cherished. They had planned everything together, and her entire family had died at their hands. Even the only antidote she managed to make was given by her husband to his beloved. She hated that man, yet could not bring herself to kill him, so she could only take her own life.
