Review Detail of Xalysian in Playful Lullaby

This was a beautiful mystery. Although I was able to guess what happened after the mystery involving the red arrow to find a treasure, the ending still hit me with goosebumps. It was beautiful, makes my heart melt from the two casts' relationship. I'm glad that this mystery has a beautiful ending. I am speechless. Nothing can describe what I felt but beautiful. Thank you for this wonderful book, Author!
