Protect Me, My Mr. PhD from the FUTURE!

A useless man wakes up as a drunken, abusive live-in husband. His wife flinches at his shadow. Her best friend schemes to steal the family fortune. Armed with a PhD and ancient medicine, he sobers up, shields her, and completes a lost century-old formula. As her heart thaws, can a man who inherited another's sins ever deserve the love he stole?
