Sihanbu Yeoningwa Bihon Saenghwal Jungimnida

Ines Eledine is known far and wide as the God of Investments, using her secret ability of reading others’ misfortunes to choose wisely–that is, until her ability vanished one day. Thinking her investing days were behind her, Ines is shocked to discover that her ability returns whenever she touches the handsome, broody master of the demonic sword, Calad Arsdeon. To keep him around, she asks him to be her fake lover…but this arrangement might not be the safe investment she thought it was.
