She Must Leave

After exercising the whole morning, Kara fell asleep during her math class.

Watching her sleeping and snoring, Arya rolled her eyes and took a coat to cover her.

When the math teacher heard her noise, he walked to Kara angrily.

Arya shrugged, "Teacher, Kara is not feeling well, but she insists on coming here."

Hearing this, the teacher felt better. He lowered his voice and told Arya to persuade Kara to go back. If Kara slept here, she would catch a cold.

Arya hurriedly nodded. During the break, Kara woke up. Arya put her arms on Kara's shoulder and teased her.

"Did you do any strange thing with your Uncle James? You are so tired."

Kara didn't get Arya's underlying meaning and explained seriously, "Yeah, Uncle James taught me how to do exercise this morning."

"You, doing exercise?" Arya was confused.

With her weak body, she would be out of breath with a pale face even though she just ran few miles.

What kind of exercise could she do?
