One day you are seen sitting at one of the tables in the library in frustration, what is in the book really can't enter your brain, the exam is coming soon and you can't remember anything that your teacher taught you, and studying in the library is your last choice even though you can't remember anything

While you are still trying to digest what is in the book, suddenly Joshua, the smartest and most popular student in this school, approaches you, puts a carton of milk next to you, and speaks

"You won't digest anything if you're tense. Try to relax your body."

he said softly, drank his own drink and then spoke again

"I happen to want to study for an exam, do you want to study together? I can teach you what you don't understand, you know"
