The test of isamu and masahiro

Isamu came to a large door, when crossing the door he saw a long corridor that was dark, he began to walk with caution since there was no sap that he could find, after walking for a while, a few meters away he could see a light from He immediately went to her and when he reached the place where the light came, he saw a large room that was empty.

Looking around the place for a clue of where his partner could be on one of the walls of the room he saw a letter when he grabbed it and seeing it immediately recognized the handwriting of his beloved kiyoshi he began to read it being prepared for everything the letter says.

Hi isamu

I am writing you this letter to tell you what can break your heart. I know it's a cowardly way but I don't want to see how you will feel when I tell you the terrible news.
