Though Heine is a grown man of around 40, he's often mistaken for a child due to his short stature and young appearance.

Heine rarely shows any type of emotion and is incredibly stoic. He acts polite towards everyone at all times, even when insulting them. He seems harsh and cold but is actually very empathetic and understanding of people. He's intelligent but does not flaunt it. The only time he loses his composure is when someone mistakes him for a child.

Not much is currently known of Heine's past. He and King are close friends, as confirmed by the fact they are on first-name basis, with no honorifics. Count Rosenberg discovered that Heine used to be a tutor at the Maria Vetsera church for children before coming to the palace, but his past before that is unknown. He was actually a volunteer tutor at the church. He has rewarded a meal each day for volunteering at the church. It's implied that he used to be a violent man due to the fact that the King told him to use the skills of the "old him" to defend his sons.
