By day, Cui Yunzheng maintains the image of a refined, upright gentleman, as pure and bright as the wind and moon. But when it comes to Nian'an, he resorts to every trick in the book: flirting, pretending to be frail and ill to beg for kisses and cuddles, and using sweetly manipulative words to put his romantic rival down. At night, he blindfolds himself with a ribbon and disguises himself as a seductive dream demon, gently coaxing Nian'an and guiding him through their intimate encounters. At first, Nian'an feels guilty and inferior, planning to save enough money to run away. But under the tender trap Cui Yunzheng has carefully woven, he gradually falls for him, and their feelings become a sweet, mutual romance.
