City of Sin - Book 1, Chapter 6

Shu Wan, the most outstanding daughter of a high-status family from a feudal dynasty, travels a thousand years into the future, becoming the new lady of the Fu family in the capital.------Her husband in name has gone overseas to explore markets, leaving behind a rebellious son whose name resounds throughout the capital.------Upon first meeting, the rebellious son speeds past on a motorcycle with his silver-white hair flying, “Isn't that my stepmother who's 6 years older than me? Skinny arms and legs, but with grand ambitions.”Before he finishes, Shu Wan leaps up and plucks him off the motorcycle with one hand, “Watch your mouth.”------Fu Yang is consistently at the bottom of his grade, especially with his Chinese language scores never passing 50.Shocked by his atrociously written exam papers, Shu Wan asks, “Are you even Chinese?”Fu Yang is defiant, “Aren't you a dimwitted academic failure yourself, what right do you have to criticize me?”Yet the next second, as Shu Wan smoothly writes down 'Ancient Prose Paragon' with a brush, it's Fu Yang's turn to be astonished.Isn't she a walking dictionary?------Fu Siyu returns from his overseas expansion earlier than expected, thinking he would come home to chaos.However, upon entering the door, he sees the usually defiant Fu Yang sitting obediently practicing his calligraphy with a perfect score exam paper beside him.And his reputedly timid wife, in a sleek black high-slit dress, confidently struts to the music, drawing the attention of everyone.But none of that is the focal point. The focus is on Fu Siyu's gaze, sharp as a knife, directed toward the dance partner's hand resting on Shu Wan's lower back, “Let go.”Note: The son is not the biological child of the male lead.

Having being plagued by same dream for the past six years, Chu Yanshen discovered a little boy who looked just like him out of the blue. It was only then did he, Chu Yanshen, learn that he had been deceived by the little lass six years ago…
