Student council president of Seonrim High and grand disciple of the traditional martial art 'Seonrim.' Raised from childhood by Seonrim’s master as his top student. He wants to carry on the master’s legacy and continue Seonrim’s martial arts tradition, but his growing love for volleyball creates inner conflict. His body, forged through years of martial arts training, allows him to deliver powerful spikes from any position. Even after a long break from volleyball, his spikes remain as heavy as stone.
