Suddenly, he was painfully aware of making a small minute, mistake that Gen was gleefully pouncing upon.

Senku's eyes widened, he looked flustered then, to the point that he drew past his star a little bit. "Gah!" He flailed, blushing lightly.

"I did no such thing!" He pointed his marker at Gen. "I couldn't have cared less about your dumb, stupid, hack career." Then, Senku pointedly looked away and licked his thumb to correct his mistake, rubbing the black mark off the wall.
