Qin Huairu of Siheyuan is spoiled by me

I traveled to an era when people lived in courtyards full of wild beasts, only to discover that Qin Huairu and I were childhood sweethearts. Faced with these beasts, I was fortunate to have a system that allowed me to write a different life in this great era.

This book has no violence, only one female protagonist, and low-key development.
