Ik-Han, Woo

우 익한 / 加瀬学

Woo Ik-Han is an ordinary human and best friends with Shinwoo, Yuna, and Suyi, as well as Regis, Seira, and Rai. He spends most of his free time on his computer and wears glasses.
A recurring gag in the Manhwa involves Ikhan's concern about his relatively short height. Initially, when Regis and Seira joined his class, Ikhan showed intense interest in the new students, leading others to assume he was developing a crush on Seira. However, it is later revealed that Ikhan was actually captivated by Regis, as Ikhan stated he always wanted a fellow 'short' friend. Throughout his adventures, Ikhan is seen giving Regis long and thin foods and candies (such as Pocky), stating that he and Regis must eat them to grow taller (a pun on the stature of the food).
His hacking and computing skills are extremely proficient. He was able to match Tao's speed when Tao tried to hack into Ikhan's uncle's police databases. He is also the best at computer games, as Shinwoo mentions that Ikhan defeated him every time. Ikhan also proves to be quite brainy rather than brawny, taking school very seriously compared to Shinwoo.
