Sono Vampir wa Tadashikunai Yume wo Miru

Louis never quite understood why others insisted on using the tactless word "vampire" to describe him. To him, such labels were meaningless, because his entire world revolved around a single, consuming desire: the person he cherished above all else. Living within a human household, Louis had been welcomed by the Kamuro family and treated as a brother-in-law. It was a life he never wanted to end. For a time, his deepest wish seemed fulfilled. He spent his days in quiet contentment alongside his beloved sister, Harumu, savoring every peaceful moment they shared. The warmth of their home offered him a sense of belonging he had always longed for, and he naively hoped these pleasant, ordinary days would stretch on into eternity. However, the fragile sanctuary he built is suddenly shattered. The arrival of another vampire named Noah disrupts everything Louis holds dear, casting a dark shadow over his carefully maintained happiness. What began as an idyllic existence quickly spirals into turmoil, forcing Louis to confront the reality that the peaceful life he so desperately clung to may be nothing more than an impossible dream.
