After being cheated on she reunited with her ex-husband

At the end of winter that year, Wen He’an lost power, was deposed, and exiled.
Born into a prominent family in Tiandu, she had once been a figure whose words and laughter stirred up controversy. Everyone said that her current ruin, her loss of fame and fortune, was all due to a single word: love.
Wen He’an had previously been married to a man of illustrious family background, power, and beauty. The marriage was a powerful alliance between families, not a romantic one.
The end of that marriage was remarkably peaceful.
What truly spurred her on was a hostage held in Tiandu by the Dongzhou royal court.
He was gentle, elegant, quiet and peaceful, but at the most critical moment, he encircled her vassals, allied with her powerful opponents, and threw the fatal evidence of power grabbing on her, while he took advantage of the situation to rise rapidly and withdraw gracefully.
When all the dust settled, Wen Hean looked at the waves of the Guixu barrier that had spread for thousands of miles and believed that he had no chance of making a comeback.
