The female protagonist, a one-year-old girl who transmigrated from the 21st century. In her previous life, she was an orphan who worked hard to skip grades, attended China's top university studying finance, completed Master's and PhD at top-tier international universities, and earned a million-dollar salary. She deeply values family love and is thrilled to experience childhood with her loving grandparents and parents in this new life. She is remarkably well-behaved, quiet, and pre-calculates her daily walking amount, refusing to take extra steps.
