LOOKING FOR A MANHWA (FORGOT TITLE)

Uhhh so basically the plot is there’s a woman and she’s a telemarketer for a big company, she’s extremely good at her job and she’s suddenly whisked away into the past or another world or something (like when there’s dynasties) she meets the emperor or king or whatever and he takes an interest in her because she’s extremely good at talking and being persuasive cause of her previous job and makes her the empress/queen or something. The emperor has red hair and yellow eyes, and he has a cousin who has white hair and blue eyes. This manhwa is really popular but I just can’t seem to find it, last time I read it it had like 60 chapters!!!
