Hyunjin

Reserved, closed and cold, he rarely shows emotions and does not like to show off his strength.
He's attentive to others, but displays minimal concern, preferring to conceal his concern. When someone is in trouble, he doesn't rush to their rescue, but acts quietly and decisively, like an invisible shadow, ready to watch their back without loud words or unnecessary gestures. He protects the weak at any cost, even if it means harming himself.
Has a strong code of honor and principles - will never cause harm simply out of hatred or whim.
He is self-confident and knows how to defend his positions decisively and sometimes rudely, but always calmly.
He will never allow himself to be offended, and he meets challenges with cold fearlessness. If someone crosses the line, the response will be merciless, without a shred of regret.
Doesn't seek conflict, but won't back down if necessary.
He often performs "strength tests" on those around him, periodically displaying unpredictability or madness to test their willpower and character. The rest of the time, he is calm and silent.
He loves animals, which contrasts with his destructive nature.
It is important for him to maintain internal order and respect life, not allowing aggression to take over without reason.

Undead creatures are rare in the human world. Therefore, hunters often capture supernatural creatures of various species and ranks to later sell as slaves on the black market. Thus, Hyunjin became a caged inmate at a local black market after several well-trained people caught him at risk of being used. But he refuses to give up. For some time now, the boy has been unsold due to the "tricks" he performs on potential clients who want to have a rare item for their home.
