A childhood sweetheart refers to a person who holds a special romantic significance in someone's life during their early years, typically during childhood or adolescence. It's often someone with whom one shared innocent affection, emotional bonds, or even puppy love. These relationships are usually characterized by a sense of innocence, simplicity, and fond memories of youthful feelings and experiences. While some childhood sweethearts may continue their relationship into adulthood and even marry, many others move on to different paths and relationships as they grow older. Nonetheless, the term "childhood sweetheart" is associated with nostalgic and sentimental feelings about a memorable connection from one's past.
