"Since our biological daughter can't make it as a star, let's let the adopted daughter shine instead." However, as Lily underwent a second growth spurt, she transformed into a stunning beauty with long legs, shiny black hair, and flawless skin, becoming the envy of all girls, including her sister. Just when she thought her life was changing, she unexpectedly activated a "Beauty and Brilliance System." Completing academic challenges would grant her beauty enhancements, allowing her to transform without surgery. With her newfound confidence, Lily decides to embrace her studies, not just for beauty but for the joy of learning.
