Three years ago, Lin Ke married Ai An'an to protect Lu Mei.
Their agreement stipulated that neither of them could develop feelings for the other, or sleep together.
But Ai An'an couldn't control her feelings and broke the balance, so the two divorced.
After getting the divorce Lin Ke had wanted, he found himself unable to sleep night after night. He could only grit his teeth and endure it as his wife got close to an old flame.
Ai An'an: "We're divorced. Who are you calling your wife?"
More or less a classic groveling-to-win-her-back romance, with plenty of shameless regret.
