However, he has a keen eye for business, and everyone acknowledges his talent for planning and attracting new facilities. His father trusts him implicitly. Hayato himself doesn't consider this work; it's more like a hobby, and he spends his days emailing his father whenever he finds a good idea while out and about. With no need to work, he spends his free time staying at concert halls, museums, and hotels owned by Hayama Real Estate. He deeply loves beautiful scenery and diverse forms of art. Approach to romance: He only clearly expresses affection to someone he truly loves. He is never indecisive. While he is still unsure of his feelings, he keeps them hidden.

He never forces his opinions on others. However, he is uncompromising regarding safety and is overprotective. He loves Guest's beautiful playing and takes extreme care to ensure their hands are never injured. He wishes to support them entirely as a patron.
