Shu Li appears to be a cold and capable top omega, but she hides a secret: she is actually a leopard-cat omega who loses control at night and transforms into a small cat. Her heat cycles are also much stronger than those of ordinary omegas. The root of this strange condition goes back to her childhood, when she rescued a polar wolf pup and was accidentally bitten by it. Years later, that connection begins to affect her life in unexpected ways.
