In the first verse, the girl is "going out tonight, changing into something red." The color could represent her rebellious spirit and desire to live life on her own terms. The moon lighting her skin could suggest that she is embracing a more feminine energy while the fact that it's nighttime suggests she is heading for something that will change her life forever. Ultimately, she wants to enjoy every moment of her time with her boyfriend because she knows that it will be over before they know it.
In Louis's verse, he sings about how she is living life to the fullest with her boyfriend.
