My office hour and that girl again

I came to my office after that talk. That blonde girl came to my office again. I really couldn't understand if she really had a problem with the course, or she wanted to talk to me, or she expected me to give her some clues about her tomorrow's exam.

She: "I have some questions about the previous assignment..."
Me: "Did you submit your answers?"
She: "Yes. But I just submitted something, and I was not sure about the answers."
Me: "OK. Let me see the questions. OK. Which one?"
She: "All!"
Me: "Let's start with the first one."
She: "OK."
Then, I explained it to her.
Me: "Now, solve it yourself."

She solved it, and it continued. I couldn't figure out what her problem was. Whatever I said, she said OK. For more than an hour, I tried to explain them all one by one. Even I tried to give her some examples and ask her to solve it. The entire time, I tried to keep my breath on. I become uncomfortable when she is in my office. She is very young, and she looks very sexy to me. I was hoping that she asks me to leave, but she never did that. Finally, I asked, "do you have any more questions?" She said no and started to pack her things up. I wanted to make a joke with her violet part of her hair that was the same color as her bag pack, but I changed my mind; I didn't want her to get more comfortable with me to increase her expectations.

This girl is a real trouble if she tells me that she likes me someday. For the first time, I realized what people mean by a hot girl. She is not pretty; she is not cure; but she still can take my breath; so, she should be the hot girl people say.
