Fragrance in the Bedchamber

The idol she'd had a crush on for seven years became a celebrity. On her way to cheer him on, she was hit by a car. When she woke up, she found herself in bed with her idol, having a good time! She had transmigrated, into the body of a stunningly beautiful empress dowager who had brought ruin to the kingdom. Her idol had become the cold, twisted regent of the Kang Dynasty. To protect her young son, the heroine muddles through and becomes the regent's bedmate. But the original body's personality was so cold and detached that she couldn't feel any of the idol's passionate love for her! Until the divine maiden ascended to immortality and her memories returned! [Both leads are chaste + rekindled romance + husband pursues his wife] The male lead is cold and aloof, yet loves to tease with suggestive remarks. He may act all high and mighty, but in the end, he still has to bow his head to his wife. The heroine is completely bewildered through the first half. As for the second half... Ahem, that's classified for now.
