Dear, I've come to recommend a novel that meets your requirements ~"Spring in the Painting Hall: Madam, the Marquis is sick again". This book can satisfy your needs. The female lead, Jiang Huayi, is cold and wise. She only treats the male lead, Song Wuchen, well. She likes the male lead alone. She doesn't like any other male supporting characters. The storyline also has a palace fight and emotional lines, it's worth watching! I hope you like this fairy's recommendation. Muah~
