In her previous life, Song Su'er was a pitiful legitimate daughter whose mother had died. Confined to a remote back courtyard, she suffered at the hands of her stepmother and younger sister. By chance, she bonded with an extraterrestrial System called Xiaomi Star. With its help, she finally stood before her father and the world, and met Shangguan Fei, the current emperor's fourth prince. Polite and courteous, he gave Song Su'er a warmth she had never known. Together with Xiaomi Star, she helped the fourth prince fight his way through the dangers and put him on the throne. But Shangguan Fei discarded her once she was no longer useful. It turned out he had always loved her half-sister, Song Qinqin, and had only approached her at Song Qinqin's behest, to gain access to the military power held by Song Su'er's maternal family. After they had her killed, Song Su'er's soul lingered around them for three years. She came to understand many things, but realized the truth too late to change anything. Only Xiaomi Star, giving everything it had, managed to let her be reborn in the body of Tian Qimei, who had just died while fleeing famine. The two joined hands once more to start over, enduring the flight from famine, building a business, and growing stronger so they could avenge Song Su'er's previous life.
It can be good
