One of the most significant challenges was dealing with my own feelings. There were times when I felt angry, frustrated, and worried about Yui's future. But as I looked at her, I saw a scared, vulnerable girl who needed my support and understanding. I realized that this journey wasn't just about helping her; it was also about growing as a person, about learning patience, empathy, and compassion.
