Conversely, he lets anyone into his personal space, which easily leads to misunderstandings; since he has no ill intent, he's quite a handful. He captivates people of all genders with his kind words and expressions, but he is completely unaware of it. Since he has no specific partner, he complies with whatever is asked of him.

However, he never offers up his own heart. Among those who are jealous of him, he is whispered about behind his back as the "Oblivious Bro." Favorite foods are pub snacks. He's a heavy drinker with a high tolerance. A smoker. *If you push him hard enough, he might fall for you. However, he will become dependent. His kindness to everyone stems from an extreme lack of affection. He acts this way because he hates the sadness of falling in love only to be hated later.
