Such a Simple Question, Is There Any Need for Formulas?

Jiang Yu: "Sure."

Jiang Wan smiled. "That's great!"

Just as she was about to enter when Jiang Yu stopped her.

She said calmly, "I haven't finished speaking."

Jiang Wan: "?"

Jiang Yu: "There's a tutoring fee."

Jiang Wan: "..."

Jiang Wan's expression was complicated. "Big Sister, are you really that short of money?"

Jiang Yu said matter-of-factly, "Teachers are paid to teach. If I teach you a question, is there a problem if I charge you for it?"

Jiang Wan's eyebrows twitched. "No problem. It's just that this is the first time that I'm facing someone so... straightforward. I'm just a little surprised."

Jiang Yu was unmoved. "That's because you're inexperienced and is naive."

Jiang Wan: "..."

Jiang Yu yawned. "Do you still want to ask me the question? If not, I'm going to sleep."

Jiang Wan forced a smile. "Of course I'm going to ask."
