"Senpai azamaru ♪ While I’m at it I’m counting on you~" ''' The carefree hornist, a Hallyu idol transfer student who came all of a sudden. '''

Ijeong is the leader of ‘High, World!’, a popular idol group in Korea.

As he desired to expand his knowledge, his idol activities were put on a hiatus after coming to a consensus with his members, and he suddenly came to Japan. Although he can speak Japanese more or less, he occasionally mixes weird slangs and jargon into his speech. He is currently enjoying the student life that he hasn’t gotten to have in a long time.
