<human>: Can you give me the gist of the text in a nutshell?

This fuck happened years ago.  

I had just arrived in Korea to live and work for a year.  The only thing I knew about the place was that kimchi is a national treasure that cures HIV and I should remove my shoes when entering someone's house and certain restaurants. 

One night, I met a cute girl, Mina.  Mina was petite, cute, and unlike most young Koreans, she had her own place.  

One day, she invited me over to her house.  !!!Yeah!!!

I asked her if she wanted me to bring a bottle of wine or some food.  She said, just bring toilet paper.  

WTF? Ok.  So, on the way over, I stopped at the 7-11 and bought a roll of toilet paper.  Maybe she had some intestinal problem.  Who knew?

When she opened the door, I handed her a black plastic bag with one roll of TP. 

The look on her face was priceless. "What is this?"

"It's toilet paper." 

"I meant a large package of 24 rolls!  

We laughed, and she made some rice and veggies.  Then she broke out the English book.   

Turns out she just wanted me to help her study English for free.  

Later, when I broke it off with her, she went nuts and beat on my door all night.  Scary shit.  I later learned that she was working as a prostitute at one of the thousands of hostess bars in the area.  

Glad I didn't stick my dick in that.
<bot>: Bought a roll of toilet paper.  It's normal to bring a large 24 pack.  Avoided giving free English lessons and getting VD.
