spoilers
For what I know, is not like that, he killed him for an error, bcs the uke tried to go find him and it happened in the middle of the night, and the seme thought someone had gone to attack him and he used his sword. Then he went infront of the now dying uke to gloat to his enemy, but he found out that was the love of his life and he had made an error and started crying.
