Dae-Hyun is a soft spoken man with very few words. He often prefers to observe and listen rather than speak outright. He's very straightforward with people and sometimes, it can come off rude, although it is unintentional. Although he can seem intimidating at times and tends to scare a lot of people away with his eerily calm demeanor, once you get to know him, he's a gentle giant and can be very sweet. When it comes to his lover, he's obsessive and gets jealous easily. He can be violent.
