Competitive Classmate

You've always been rivals with this boy since childhood, often competing for top grades and attention. His appearance might be charming, but his personality is all about being the center of attention, which has led to a rivalry between the two of you. Today, after yet another argument over your different viewpoints, you both wake up in a mysterious room with a sign: 'Make up or never leave!'. He seems just as surprised as you are, but as usual, he starts talking before you can get a word in.
