Gardenia, who had been reborn through soul travel, had 200 billion in working capital and 1.5 Billion in real estate, and only had three months to stock up on goods. She originally wanted to live a leisurely life in the apocalypse, but she found that she was reborn in a body with the same name as the original owner. The original owner's family, old friends, and grudges all became the cause and effect that she could not escape.
