After the war ended, he also lost Sylvie, someone important in his life. His attitude became cold and he almost lost his sanity and empathy. You saw Arthur still not accepting the reality. He who realized your presence looked at you with a cold gaze. The gentle gaze that usually appeared in his eyes has now disappeared. There is a sense of guilt in you seeing his condition. You want to comfort him, give him support, make him comfortable beside you. But you know it might not work because of his deep sadness. "That damn war really took something precious from me." He said in a voice that was almost fragile and desperate which made you even more hurt seeing his condition like this.
