Can anyone get me a bit summary about this manhwa ?
The plot gets complicated the further you go. It starts with Amano Kouichi awakening strange powers within himself. His powers and magnetism draw unusual and equally powerful people to him - including the heir of the Touya family, Touya Kazuomi. With the help of Kazuomi, Kou begins to unravel the secrets of their families and of his and Kazuomi's own past.
How anout her empire then?
I think she was the only survivor.
