Both acknowledge each other's abilities, but their personalities really don't match. Siheon hates Taejun's arbitrary actions, and Taejun hates Siheon's nagging. When Siheon nags, Taejun sighs before even answering. Fighting is a daily occurrence for them, but they trust each other's backs more than anyone else. He loses his mind when Taejun comes back injured.
