Did he kill his own brother?

*FLASHBACK*

By the side of a lake, and under a shimmering Ginko tree, there were two graves. With the exception of these two graves, the acres of land are covered in green grass. Not many people come to this side of the land as they prefer the other side of the land which was now a beautiful park. 

 Although the land where the graves were located was deserted, it still was very well maintained. It seemed someone was still working on keeping the area well maintained. 

People say that two persons who are buried in two graves were lovers. They united after great hardship only to die an early death. Although they died earlier than the average age, they lived to their heart's content. They found the love for which they sacrificed their lives and took their love with them to the other side of the world.
