Secrets of the Heart follows Kato Shi, an ordinary young woman whose life appears perfectly balanced. She enjoys the trust of close friends and the deep affection of a loving boyfriend who works as a photographer. Yet beneath the surface of her peaceful daily routine lingers a quiet emptiness she cannot quite name. As she begins helping her boyfriend with his shoots, she steps into unfamiliar social circles and encounters a variety of intriguing people. Through these new experiences and meaningful choices, Kato gradually uncovers hidden layers of her own desires and identity in this emotional, female-protagonist adult visual novel developed by FallingDay.
