Actually. For being the oc site I haven't posted a lot of my own personal stuff have I!
This is Leo, protagonist of what were supposed to be a short self indulgent comic based on manhwa I like (trashy fantasy romances for women my beloved). But then health and writing block got in the way.

Anyway so Leo is a trans man who's the leader of a mercenary group, having been cursed by a witch to feel everything twice as strong for his supposed heartlessness. This means that he has often extreme mood swings and can get stuck in feedback loops of emotions. But it's been a few years since then so he has mostly learned how to deal with it.
The story takes place after he was stabbed by a would-be assassin and is saved by a passing aristocrat, the Duchess Wisteria. And he falls head over heels at first sight and makes it his mission to learn about her while he heals from almost dying.
Personality wise I'd call Leo throws himself into any situation with his all, partly because every emotion feels too big for his body but also partly because he's a bit of a daredevil living for the rush of a new experience. Though just because he does get himself in dangerous situations doesn't mean he's careless- no he's very much someone that can infer things from very little. Leo became the leader of his mercenary guild by being able to see peoples strengths and weaknesses and so assigning them to where they'd most be useful.
