The first time kyuhyun meet jongwoon is when he was introduced as the newly added member to a rising popular group,Superjunior05. "nice to meet you,I'm kim jongwoon but my stage name is yesung""ah, jongwoon, nice to meet you too""hyung" yesung said. "hyung?" "yes,I'm your hyung, I'm at least 4 years older than you" yesung pouting from the new maknae mistake,slightly huffed. 'are you? He look younger than me' thought kyuhyun. With a reflex kyuhyun ruffled jongwoon hair that make jongwoon pouted more if it's adorably possible.   " yes,Hyung".
