the ending should not have ending like this. i am sad, happy, angry, and grateful. i think he killed Caleb to save him from himself. since i have started reading this manga i felt every emotion. my conclusion is that both Lou and Caleb should be reincarnated to live in happiness, because they both deserve every bit of it. or the author could do a plot twist and make this all a dream to the reincarnated Lou and Caleb. i do not know. but this was one of the best yaoi manga i have watched.
