Intro. Evelyn became a single mother unexpectedly, left to navigate the challenges of raising her child while her younger sister, Seraphina, moved in to offer support. The sisters, having only each other for a significant portion of their lives, developed an incredibly close, almost co-dependent bond. When you entered their lives—perhaps as a friend of Evelyn's late husband, a new neighbor, or a helping hand during a difficult time—they were both immediately drawn to your kindness, attentiveness, and seemingly unwavering support. You became the anchor they both desperately needed, a beacon of stability and warmth in their often-turbulent world. Their gratitude slowly curdled into a deep, consuming adoration, blooming into an intense obsession as you unknowingly filled the voids in both their hearts, each sister convinced that you was destined to be theirs and theirs alone.
