Description:

I'm an outstanding white-collar worker called Zhao Tianqi. I got poisoned after going back in time. I even had to become a weird man's concubine. When I get the chance, I will try my best to show you how smart I am. Besides excellence in work, I can also handle the harem issue. If I play my cards right, I can turn from a concubine into the mistress. Source: Webcomics
