Review Detail of tudoro in Heart of Flowers Sword of Thorns

This is an ongoing story and I must say - it is such a lovely story - I do not know yet how it is going to end, but I feel the first chapters are the loveliest in the manner that they build the characters and set up the background for the story. Right now I do not understand why the rating if for 18 and over. Not a lot of smut -maybe for the upcoming chapters?
