It's not that Song Ci had a sudden burst of compassion like a saint, giving the concubines a way out because she pitied them.
Pfft, there's no pitying them, dressed in finery, surrounded by servants, with the backing of the Prime Minister's Mansion, their only job is to look pretty. Where's the pity?
Waking them up was entirely because she found Song White Bread unreliable. Although he heroically drank the Infertility Medicine, ensuring no woman could come to acknowledge him as a father, he kept bringing woman after woman into the mansion, turning it into a mess, which she couldn't tolerate.
So, she gave these two such a mission, it's a clear path and mutually beneficial. After all, without children, they can only remain clinging vines, tightly attached to Song White Bread and the mansion, growing old and losing their charm before getting off the carriage, which is truly too tragic.
