The Return of the Ex-Wife

Annis, a knight, married Marquis Devon Pizetra out of respect for her late mother's wish. As the lady of the house, she brought wealth to the family by successfully managing the finances. However, the incapable husband Devon spends her hard-earned money on his ex-wife, who is pregnant with his child. Devon asks Annis for a divorce but forces her to stay on the estate and continue to manage family businesses.

When Annis was broken by her husband's betrayal, she encounters Rowan, an old acquaintance and fellow knight who seems to have feelings for her that's been kept hidden for a long time.
