Searching for a manga about a viscountess and her half sister, the viscountess inherited everything from her grandfather while the rest of her family and the many bastards her father has got nothing. Well, the grandfather forgot one and her father goes on to use the halfsister to exhort the inheritence from mc. There Was also a side plot about the prince trying to get mc Land to give some upstart nobels since every Land inside the kingdom is already distributed. Hope i get a reply this time...
