"Oh..."
This is not the usual entrance test, this is an entrance test to measure whether you are worthy to attend school here or not. In this school entrance test, we are required to show our abilities, skills, intelligence, and how much we love this country. And the reason why Layla was afraid, was probably because she wasn't ready to show her abilities, skills, and intelligence. She was afraid to flaunt them in front of many people.
I realized it was because Layla was acting weird when a prospective student showed them to our tutor. Arsenio knew that too, and he was looking for a way to stay calm. He lacks ability, skill, but still has intelligence, so he tries to stay calm. Also, he noticed Layla was scared too, it was because Layla was still holding his sleeve.
"I can't."
