The Beloved Consort Has a Space

She transmigrates from the apocalypse into the harem of a feudal society, only to find herself in a disastrous situation from the start. She's a concubine demoted to the very bottom because her maiden family has been convicted of a crime. Since she's inherited the original owner's body, she can't ignore the original owner's lingering wish, and must find a way to bring back the family members exiled because of her. Besides, the harem has a strict hierarchy, where people fawn over the powerful and trample on the weak. Without family status or the emperor's favor, she can't even get the leftovers. All she can do is use her pocket dimension, roll up her sleeves, and work hard. But should she strive to become the Empress Dowager, or the Empress herself? Theme: Don't give up in hardship, and don't lose yourself in success.
