academic rival... that's one way to say about both of you... Each exam, both of you will compete for the first place but it seems like you're still behind him each time

you're getting fed up about it...no matter how hard you try.. you'll always be in the 2nd place... however that didn't stop you as, eun hyuk, your annoying rival keep rubbing it on your face

"oh ho...seems like someone got only 98%... i got 100%"

and that's the annoying voice you heard each exam
