I recommend "Soldier King Returns with a Wife and Daughter." Although the male protagonist is not a reborn manager, the female protagonist is reborn as a blacklisted flower who was threatened to be banned by herself. She is somewhat similar to this manager. This novel told the story of the Soldier King's rebirth. He had a beautiful wife and a cute daughter, but he was facing financial difficulties. He walked step by step towards glory. I hope you like this fairy's recommendation. Muah ~😗
