Spencer Reid and Amelie Scott have spent the past five years navigating the complicated world of co-parenting their daughter, Baya. They were once in love, but their relationship unraveled after Baya's birth, leaving them as partners in raising their daughter, but little else. But when old sparks begin to flare and a shared love for their daughter draws them closer, Spencer and Mel are faced with the question: can love truly be rekindled, or is it forever lost in the ashes of their past? As Spencer and Mel continue to walk the delicate line of being parents and maybe something more, they're forced to confront the pain of their breakup, the cracks in their relationship, and the feelings they've kept buried for years. Can they rebuild the trust they once had? And, most importantly, can they put aside their fears to give love another chance-for Baya's sake, and maybe for their own?
