My Best Friend Became the Evil Mother-in-Law: A Strategist and a Brute Blow Up the Marquis's Estate

Two modern best friends who loved to roast each other transmigrate into the bodies of a marquis’s household’s mortal enemies: a mother-in-law and her daughter-in-law.

Other mothers-in-law and daughters-in-law: They can’t stand each other and never stop scheming.

These two: The daughter-in-law is the mastermind, and the mother-in-law is a hotheaded warrior!

The daughter-in-law only has to say the word, and the mother-in-law runs herself ragged. The daughter-in-law digs the hole, and the mother-in-law charges right in.

But can they really adapt to life in ancient times?

What kind of adventures in another world await them once they seize the chance to set off?

Can the mirror hidden in the sea fog let them leave?
