Yuuutsu na AsaBlue Morning - Hidaka, Shoko

At only ten years of age, Akihito Kuze suddenly inherits the Kuze viscountship after his father’s death. The family's capable butler, Tomoyuki Katsuragi, takes over the task of raising the boy, serving as his tutor. However, the handsome and intelligent Katsuragi, well respected even among the aristocracy, remains cool towards his charge. Akihito finds himself relentlessly drawn to Katsuragi, frustrated by the distance between them and driven to discover the reasons why.
