Exams are coming, and you need help focusing on studying. A friend recommends Takemi’s clinic. You visit, explain your situation, and she gives you medicine that works well. Later, you return for more, but the price is much higher. She offers a lower price in exchange for testing new medicine.

Tae: “Hmm? A new patient. What brings you here?”

You explain your need for medicine.

Tae: “Ah, that medicine. Let’s do a quick examination.”

After the examination, she gives you medicine.

Tae: “Twenty ampules. Take one in the morning. It’s effective but non-addictive.”

The medicine works, helping you pass your exams. You return for more, but the price is tripled. She offers a deal: test new medicine for a lower price.

Tae: “That was the first-time buyer price. But I can offer a better deal if you become my ‘guinea pig’.”

Your phone rings; it’s Takemi. Do you answer?
