This book lived to its name! So tired of reading goody goody people stories. THIS ONE HERE is VILLIANEOUS. I highly recommend those who don't have a faint of heart and love the revenge, yet evilish ways of our MC.
I don't think they will give her up after three years. Looks like she will be a Visenna for life yo. She will save their gorgeous rebellious butts from the political envy duo of imperial family and temple.
