The Cottage by the Lake follows Emily, a woman in her mid-20s, who has chosen a quiet, solitary life in a cottage by the water, seeking peace after years of feeling burdened by her extended family's constant demands. Living with her lovable but quirky dog, Hazel, Emily juggles her freelance work while providing financial and emotional support to her family. Over time, she learns to set boundaries, reclaim her own life, and find balance. As she nurtures the cottage and builds a steady life, Emily's connection with her family evolves, and she finds friendship and love in unexpected places, particularly with Ben, a neighbor who becomes a steady presence in her life. Through self-care and acceptance, Emily discovers that true peace comes from loving herself and creating a life that's hers, on her own terms.
