The heroine and male lead are senior and junior sect siblings.
The male lead, Su Che, is the fifth senior brother.
The heroine, Sang Nuo/Qing Luo, is the junior sister, a sickly, scheming young woman.
The male lead is hopelessly in love and tries to steal her away. He creates all sorts of opportunities to spend time with her, and constantly badmouths Xiao Yiyun.
In public, the heroine acts like a green tea and a white lotus. She loves wearing white, even though she actually hates white and black clothes. Her favorite colors are pale blue, blue-green, orange-yellow, and persimmon red. In private, she returns to her true self: scheming and sickly.
In front of others, the male lead is cold and aloof. In front of the heroine, he is honest, loyal as a dog, lively, and talkative. He knows her real personality and what she likes. That’s why he deliberately gives up his favorite black clothes and wears outfits in all the colors she likes, such as pale blue robes, red, orange-yellow, and blue-green. Other people always say he’s secretly flirtatious, but only he knows he’s doing it all to attract the heroine.
