The book is about a girl named Delsa who, on the night of her twenty-fourth birthday, rereads the letters she wrote to her lover Ryan during her treatment and remembers a time when she was struggling with a severe emotional crisis. She puts her feelings and emotions on paper to clear her mind of the toxins of the past.

The letters narrate the stages of mourning, memories, wishes, emotions, and lessons that Delsa has learned from separation. By traveling inside, Delsa tried to get to know herself better, embrace her inner child, face her shadows and flaws, and create meaning for her life.

This book emphasizes that we must face our realities, wounds, and anxieties and not suppress our emotions, we must take responsibility for our own lives, love ourselves, and accept the facts of existence.

That no matter how much our loved ones are with us, there is still an inherent distance between us and the world around us. One day we will leave this planet, so we have to accept the quasi-deaths. The pen of our destiny is in our own hands; So we have to take responsibility for our lives and pay the price for our choices. We also seek our own meaning in life so that we can continue to be committed to our lives and goals despite all the challenges and difficulties ahead.
