Dongfang Qinlan was saved by her future husband Bai Luo (cameo by actor Zhao Yibo, who also played Li Quzhuo). In the story, he is also her childhood sweetheart, the painter. 

It's presumed they marry, and later, she's talking to her son Dongfang Yuechu (ML from Red Moon Pact). She doesn't know what happened to Huai Zhu (she's living kind of hermit life in the mountains), but she wants her son to remember their enemy is Jin Ren Feng.
