The Delicate Noble Consort

Yun Jiao never expected that going with her friend to catch her friend's boyfriend cheating would somehow lead to her transmigrating into the past, and becoming a noble consort. Although transmigrating into the imperial harem is a bit of a trap, she gets free food and lodging, as well as a house. It's much more comfortable than her modern life, with the only drawback being that the emperor is a little difficult to please. But for the sake of her future, Yun Jiao decides she must cling tightly to his favor, or she'll lose her comfortable life.
