Reborn at 18: The Great-Grandma Takes Charge Season 4

Eugene is still devoted to her late husband, the war hero Seth Johnson, but he seems to have come back in the body of Arthur Sterling, the strange and withdrawn heir to a rival family. Arthur was born with a part of his soul missing and has always drifted through his own private world, yet a pull he cannot explain keeps drawing him back to the widow who once loved him. Her fiercely protective grandsons see only an eccentric stranger bothering their great-grandmother, and they vow to chase him off by any means necessary. What starts as a series of awkward mix-ups slowly exposes a buried history of sacrifice and secret missions.
