Something was off

Meanwhile, in Sebastian's room. 

"This isn't for a kindergarten." Axel almost tossed the papers across the room, gazing at them in dismay. "Shouldn't kindergarten lessons be all about colors and counting? What the hell is this?"

Axel had been trying his hardest to help Sebastian, even reading how to solve this "simple" problem, but to no avail. His brows rose as he looked around the room, cocking his head to the side. 

"Where did he go?" he wondered, remembering his nephew excused himself to the bathroom. But until now, he didn't return. 

"That little ancestor… did he sneak away from his homework?" A sour expression turned up on Axel's face, dragging himself away from the table to check his nephew in the bathroom. 

As a courtesy, Axel knocked on the bathroom. 

"Little ancestor, are you okay?" he asked after three knocks. "If you don't answer, I will have no choice but to go in, alright?"
