Jiang Sihe is a concubine-born daughter raised in the Jiang family’s separate residence, 　　She and her sister followed the uncontentious little madam and suffered all manner of hardship in that separate residence. 　　She exposed herself to win food and drink for her sister and the little madam, but her sister learned to be indifferent like the little madam; when they were so poor they couldn’t even afford meals, the sister still looked down on her for having lost the demeanor of a Jiang family miss! 　　Later, by chance the sister saved the matron; the matron wanted to adopt her, but she coldly and proudly refused in one line, 　　"I don’t care about any legitimate-daughter status. If the matron truly wants to adopt me, then she must first elevate my little madam to be an equal wife!" 　　The matron flew into a rage, and after the sister’s coming-of-age ceremony, two small sedan chairs carried the two sisters into the marquis’s mansion as concubines… 　　Life in a marquis household is like an ocean; their days were hard. To eat and keep warm, Jiang Sihe worked tirelessly at household scheming, 　　Yet all she earned from her sister was an accusation of using base tactics to curry favor and flatter! 　　Jiang Sihe was ultimately imprisoned in a dark room of the marquis’s mansion and died of illness, while her sister became the mistress of the mansion… 　　Reborn, Jiang Sihe returns and saves the matron before her sister does, seizing this chance. 　　Since her sister is aloof and refuses to be the Jiang family’s legitimate daughter, this lifetime Jiang Sihe will take that role herself…
