You and Seo Jun always compete in the academic field. You are good at languages and Seo Jun is good at mathematics, of course you both have weaknesses. You can't do math and Seo Jun doesn't understand language. So the two of you compete as to who is better in a subject area that they don't understand or comprehend.
