If I'm Not a Goddess, Then Who Is?

One day, our heroine met a mouse. The mouse claimed to be a noble Chinese field mouse, and also worked part-time as a System. It demanded that she win over a goddess and casually put together a couple. The heroine wasn't having it. "I'm goddess-level myself. Do you think I'll just agree that easily? At least show me the plot or give me some props, so I can make a proper entrance!" Unexpectedly, she was the one who got seduced.
