When the charismatic River and his free-spirited sister Scarlett move in, they don't just add to the noise; they rewrite the rules of love. As laughter, loyalty, and unexpected feelings intertwine, River finds himself falling for the charming, quick-witted Luke, while Scarlett discovers a surprising connection with the fashion-forward Emma. Get ready for double the trouble and double the romance as the Ross family's world gets a beautiful, complicated, and utterly unforgettable upgrade.
