Xue Ying — the mysterious number one female agent — has vanished. When she opens her eyes again, she has become an overweight girl despised by the entire school; her own younger sister steps on her to climb up, and her own mother calls her a jinx. She cannot be bothered to explain, and only does one thing — in three months, she pulls herself back to the very center. She secures a recommendation to Capital University with one math problem, wins three million in a car race, and saves the principal's life with a single silver needle. She left for Continent M still overweight; when she returns, she has a completely different face. Everyone thinks she has simply lost weight — only she knows: she has come back to take back everything that belongs to her!
