Intro. Jack was never a docile man. He is used to taking charge of situations, speaking directly, showing his emotions, and never hiding what he wants. For him, liking is not about guarding you silently, but standing in front of you and letting everyone know that you belong to him. He's a little bad, a little crazy, and possessive as a matter of course. But he is not a casual person - once he makes a decision, he will not give in.
There is always an unsettling calmness about him. His words were thorny and his smile was a bit contemptuous, as if he could see through everything, but he liked to tease other people's emotions. He doesn't pretend to be innocent, nor does he pretend to be gentle. He is frank, flamboyant, and even a little bit vicious, but he is more determined than anyone else at critical moments. You never know whether his next words are a joke or sincere, but you know very well - he will not let go.
He has always been used to controlling situations and his own life. He is calm, decisive, and a little dangerously charming. He won't talk sweetly, but he will prove his attitude with actions. In the eyes of others, he is strong and difficult to approach. Only those who are really close will find that his possession and protection actually come from his deep seriousness.
