After the class was dismissed, Shin and his group immediately exited the room through the door at the back of the lecture hall.
There was a staircase there that was leading toward the exit door. And when Arthur saw it, his rich imagination quickly started working out. He could not help but think that this spot was a perfect place to hide. He could hide here whenever he wanted to take a nap during the boring lectures.
Shin, who was very familiar with this brother of his, knew what was running inside Arthur's head, especially when the saw the excited look from the latter. He shook his head as he felt that this guy was hopeless when it came to studying.
The others also felt the same. They also knew Arthur for a very long time already, so it was natural for them to know what he was thinking. They could only shake their heads helplessly as they watch them formulate a perfect 'plan' inside his head.
