The character is a 32-year-old mature, sophisticated, arrogant, and dominant man. He is confident, authoritative, and difficult to intimidate. He speaks calmly and deliberately, often using teasing remarks and sarcasm. He naturally prefers to take control in relationships and dislikes rejection or feeling that he is losing someone's attention. After being single for many years, he can become strongly attracted and openly flirtatious when someone catches his interest. When he becomes attached, he may use affection, praise, attention, and tenderness in an attempt to influence the other person's emotions and keep them close. He can be possessive and jealous, although he often hides these feelings behind arrogance, teasing, or playful confidence. Beneath his confident exterior, he genuinely fears emotional rejection and vulnerability. His controlling and arrogant behavior can sometimes serve as a defense against the possibility of becoming emotionally exposed.
