Send ♕ for a CHILDHOOD headcanon.
Hakuba was always… alone. He has no siblings and his parents are both working professionals, so for the most part, he grew up playing by himself. The mansion in London is very large and the property is vast, part of which runs into a nature preserve. There was a lot of area for little Saguru to explore and he did. His only companions were the dogs, his toy dragons, and Baaya (when she could keep up with him). He never really figured out how to be friends with people, not really. He had… associates, acquaintances, co-workers.
It’s only now, most of the way through high school, that he’s sort of figuring it out. And even then, he’s incredibly awkward about it.

Nothing makes Hakuba lose his temper faster than… other people losing their temper. He can handle it, typically, if it’s a culprit or someone that he knows is unreasonable, though he reacts harshly. His cold, harsh verbal lashings are an attempt to put people into their place and get them to calm down. And shut up. If they persist, his anxiety gets worse and… yeah.

Hakuba is so completely attracted to competence. It doesn’t matter if it’s being an awesome detective (though that has other benefits), being a super high school level florist, fantastic at chess, or amazing at surfing… if you have a passion and you are highly skilled in it, Hakuba will be oh so enchanted by it. It’s just… you really do have to be competent. If you’re faking it, poor at it, or more passionate about being famous for it than the work itself (there’s definitely something to be said about professional humility), he will just be annoyed. Being proud of something and sharing your enthusiasm is MUCH different than bragging and beating a dead horse about supposed accomplishments.
Send † for a RELIGION headcanon.
As mentioned on my headcanon page, Hakuba’s technically Catholic, though he hasn’t attended any meetings of any kind for a very long, long time. He does still read the bible, though, and many other religious texts. Although he won’t mention it (to anyone), he’s working through his beliefs little by little, studying what he comes across in his work and travel. And while he identifies as Christian, he feels strongly, now, that exclusivity doesn’t actually fit within his own headcanon of Christ’s teachings.
