Kotori's reaching her limit as she tries to woo Umi. Too bad she's not a math major cause she doesn't know what this limit is. Or the one time Nico's advice actually paid off, please don't think this is a trend. "Wait, if it isn't Honoka then… Umi? OF ALL THE PEOPLE UMI? POSSIBLY THE ONLY PERSON ON U'S DENSER THAN ELI." Was Kotori's crush really that obvious for Nico to guess?
