Bab 137: World 5.13

"Mr. Sun Doyoon?"

"Sun Doyoon?"

"Mr. Sun Doyoon?!"

Doyoon flinched, and from the outside of the window, his gaze went back inside. Back to his angry physics professor calling his name. 

He bolted up, "Y-Yes, professor?!" he exclaimed, looking at his classmates' expression.

"I've been calling you since earlier. What happened to you?" The professor lowered his voice. 

This is very rare for Doyoon. He's the top in this subject and he never failed to amuse his professors. "What is wrong with you? Are you not feeling well?" 

Doyoon immediately bowed his head. "I apologize, it's just that…my head suddenly hurts.." he clenched his fist tight, hoping that the man would believe him.

Their professor closed the book and gazed at Doyoon. "Then, go to the clinic to get some medicine, you dumbass! How would I know what you're feeling if you're not gonna tell me, huh?" He pointed to the wide-open door. "Get out..now!"
