[Fiery heiress vs. cool, cocky young master of the powerful Pei family]
Six-year-old Shen Tangyin is ostracized at the orphanage until Shen Chaoyang takes a liking to her and adopts her.
The sunny boy in a white shirt crouches down in front of her. "Will you be my little sister?"
From that day on, Shen Chaoyang is just like his name, a beam of light illuminating her life.
Shen Chaoyang dotes on her and spoils her, but when his biological sister arrives, Tangyin is sent overseas, taking her first love with her.
After returning with a forceful determination, Shen Tangyin works desperately to make a life with her brother, but her adoptive mother opposes her, saying an orphan like her has no right to marry into the Shen family. Then she realizes her brother has only ever seen her as a little sister. Heartbroken, she marries her fiance. By the time her brother wants to be with her, she's not only the little princess of the reclusive, century-old Xie clan, but also the wife of his best friend.
One day, the young master of the Pei family slips his hands into his pockets and stakes his claim: "Honey, the baby's hungry."
From then on, her adoptive mother regrets everything, and her brother's heart is broken.
