My Fiance Forced Me to Go Under Lab Test, I Become Mute

At the engagement banquet, Eve, the adopted daughter suddenly collapsed and convulsed, accusing me, "Audrey, why did you switch my medicine again? Just because your fiancé gave me a bracelet?"

Mom and Dad scolded me for being cruel. My fiancé angrily rebuked me for never learning my lesson and left me overseas to atone by testing drugs for Eve.

I lived with lab mice, taking hundreds of pills a day, my body covered in needle marks.

Three years later, the miracle drug was successfully developed. I, however, had gone insane.
