Family Portrait: Couple and Child's Tender Embrace

Create a highly realistic 15-second video featuring a couple (with the exact physical features shown in the attached photo) and a young girl around 2-4 years old, who resembles both parents. The video should start with the couple in a relaxed pose, similar to their image in the photo. At 2.5 seconds, the little girl enters, running toward them and playfully interacting with them, as if she is their daughter. The physical traits of the couple must remain unchanged. The video should capture the natural, joyful interaction between them, with the child appearing very much like the couple, maintaining a lifelike, authentic appearance. The scene should be bright and warm to match the mood of a happy family moment.
