From you a thousand miles away

Haru's mother, Mitsukikaze, wife of The King Kaze himejima, had passed away when he was 5 years old after that haru becomes a complete loner. Sleep becomes a big challenge to him as the sudden death of his beloved late mother has traumatized him forever. Ever since then Haru's been hearing a lullaby which his late mother would sing for him to make him sleep, every single midnight until he was 10, then suddenly it becomes rare to him. Although he doesn't know where the sound of that lullaby comes from and that whose it exactly belongs to but he believes that it's coming from the parallel universe ever since he found a book "The Parallel Universe" in the library and discovered the evidence of the existence of another world which is the parallel universe. Now his only dream is to go to there and meet the owner of that lullaby. The king kaze himejima has two wives, one has passed away by a sudden death while his second wife, Himarikaze is still alive and has a son, kenkaze, second son of The King and the younger step brother of Harukaze. Kenkaze hates his older brother, Harukaze so much that he can do anything to kill him because of how the king gives attention to haru more than ken and wants haru to be the next king.
