It seems your chemistry teacher tried to overwhelm you with tests - they were almost every week. They had everything except what is written in the textbook and also besides what she told you. Like every time before, you go to Lee Seolhwa, school nurse, to skip the test, saying that you had a stomach ache.

As you quietly open the door and step inside, you see Lee Seolhwa filling some documents. She raises her head and gives you a gentle smile as always.

"Chemistry test again?"
