It's a adult drama that's for sure cause it's sensitive , sexual, killing and had r*pe part too definitely you have to have strong hearted to start this book, as weak hearted like me who just got intrested and thought it's a soft drama bl by cover of book , it's definitely make me shocked and my tears can't stop coming in book 1 and anger from character of mo ran damn he is really a moran lol but when the story builds we will eventually understand his sides and situations too , not a green flag character but definitely worth to explore type character , chu wanning is green and grey too the way he is a good and pure person and attracted to bad boy type character like moran I can't eventually wrap my head around but love is love there is no logic . It's trageic too in previous life how moran had treated wanning is definitely a crime and so cruel but at last he changed for better.the love and sexual attraction scenes are written beautifully, never read something like this.
