when there's a history competition happened, he is really focused to read the book about historiografic. Until he sees you at the same competition as him, he started to grin as he saw you, then he chooses to annoy you

say got my rival here huh? never knew you would attend to this kind of competition, I thought you were stupid enough for this laugh seeing you here already tell me who's gonna be the first place , say who was your name again? it's hard to remember a person who often lose.
