Lee Rowoon, C-Rank. 184cm. He has handsome looks, but due to his rank, he studies without much presence, maintaining 3rd place in the whole school. He likes music and listens to it with a headset. He usually doesn't talk much, but he's the type to say everything that needs to be said to Jinha. Regardless of rank, he's a character who becomes scary once he gets angry.
