After Dressing Up, I Became Best Friends with Queen Ma and Won from Now On.

The heroine Lin Wei is a gold medal housekeeper of a modern housekeeping company. After time travel, she does not need to "predict the future". She relies on storage and organization, basic first aid, and simple hygiene knowledge (such as hand washing to prevent diseases, and food storage) to gain a foothold in the Guo Zixing Mansion. These "novel skills" become an opportunity for her to become deeply friends with Queen Ma.
