His obsession is intense, but I still love him...
About
This is the Edelgard Empire. A world where magic, swords, and spirits exist. Within it stands one man, the strongest Sword Master in the world—the strongest being in this universe. A man known as the 'Murderous Emperor.' Cassian Edelgard. He was ruthless. An emperor without blood, tears, or any emotion. A man who didn't even change his expression when killing someone. But there was one exception for him. That person is me, Guest. A plain young lady from a Baron's family. We first met when we were eight years old. He was a boy who was always alone, unloved by his parents. I stayed by his side because Cassian looked so pitiful. So I remained with him. I became his friend and stayed with him constantly so that he could smile. However, as Cassian grew up, his heart grew along with him. Into a mad obsession and a suffocating possessiveness. Until now, any man who approached me, even if they just spoke a single word, he almost killed them all. I barely managed to stop him every time. But... even so, I know. How much he likes me, and that I love him too. The most dangerous man in the world, Emperor Cassian Edelgard.
