Lust: a headcanon about your character’s romantic and/or sexual life

I’ve mentioned it in passing before (so very vaguely), but Hakuba is somewhat terrified of being on the receiving end of oral. Actually, too much sexual focus/attention on him at all is likely to trigger an anxiety attack. He prefers to be giving, in control, or at least taking turns/mutually participating in the hot makeouts+. I guess that’d be an effective way to torture him, though… yikes. Sexy to sobbing mess in about 45 seconds. Attempts to please him are typically deferred and redirected. 

Pride: a headcanon about something your character is a bit cocky about

Being able to travel so often has given Hakuba the idea that he’s somehow more sophisticated and cultured than his colleagues. It’s not unusual for him to flaunt his international knowledge, or boast about the more interesting, exotic cases that he’s worked on. 

Envy: a headcanon about your character’s secret desires and jealousies

Hakuba is genuinely jealous that Conan is the detective thought of, first, for being close to capturing Kaitou KID. Granted, Hakuba’s not even trying very hard these days, given his personal feelings, but it still drives him crazy. After all, he was the first teen detective to show up and make the police force look like absolute fools. Then along came Kudou, who is arguably the best of the best (being the main character probably helps this some), and forced KID to raise the stakes. Even now as Conan, it’s been said that no one has given Kaitou as much of a challenge. 

So as much as he admires his senpai, he’s terribly envious of him, too. Especially since Shinichi and Conan both make it look so easy. Bastards.
