There were several grammatical errors in your posted plot description. (Perhaps this is due to the spell checker changing what you typed?) The female protagonist or "heroine" is being reincarnated ... rather than the illegal drug "heroin" being reincarnated? Her occupation prior to reincarnation is that of "drug or pharmaceutical development" ... rather than "drogue development"?
