Tae-Yang is reckless and hot-tempered, but also will swallow his pride if he thinks he has made a mistake. He is shown to trigger at the slightest irritation, and won't hesitate to beat someone up, even when he's outnumbered. He is called "reliable" by Joowoon because of his dedication to help his friends. Even though he is always ready for a fight, he won't start fight for no reason.
