Appearance

In the present, He still looks somewhat similar but more mature as a young man.

Personality
12 years ago, when he first entered the tower, he was described to be a wuss by Hyeonu (a detail he's embarrassed about). In the present, he seems to a bit more confident and knowledgeable over hunter's affairs. He's also very aware of the Ares Guild's dealing and to steer clear to causing problems with them. Sihyeon Kim was frustrated of being weak and relying on Hyeonu Kim, so he approached Cheonma, who taught him the Sky Naming Blade- First Stance: Extreme Strike.
