The Unruly Empress

Empress Seraphina Shane of the Kingdom of Veridia is despised by Emperor Conrad Lancaster for her postpartum weight gain and is framed to death by Lady Rosalind. A modern medical school graduate is transmigrated into her body, equipped with a shopping system. She loses weight, becomes beautiful, repeatedly crushes her opponents in the palace struggles using modern technology, and helps the Kingdom of Veridia defeat the Northern Horde.
