OMG, I Am Trapped, Save Me!!!!!!

Chemistry is quite a difficult subject and you can not even start attempting a chemistry exam without having the appropriate knowledge to solve a question. Well, this post is not at all about chemistry. Its about a girl who attends the same chemistry tuition classes which I attend. I didn't even know her and I did not even wish to know her actually.
So, the problem started when one day, after class, she asked me to bring her some snacks from the shop situated just in front of our tuition centre. She gave me a few hundred rupees. So, I said OK, no problem and then I brought her whatever she wanted. And I thought that this would be the end of it. But no, absolutely not, it did not end then and there.
The next day, after class: I am talking to my friends and then she comes to me and says: "Yaar ice cream la do, is k liye bhi la dena" ( pointing towards one of her friends). In my head I was like : "Yaaaaaaaaar :/, why me. Now I cant even refuse or else a lot people would think that this guy is a rude freak". So I brought her whatever she wanted again. My friends were laughing at me like lunatics.
And just yesterday, just before I could enter my class, she (that horrid little beast) saw me, she pleaded: "Yaar achay bhai please pani ki aik bottle la do, please achay bhai". Then I said: "Yaar, there is a whole lot of other guys just standing idle outside, ask them". I think she didn't even hear me and she continued like please please please la do. Totally exasperated, I brought her a bottle of water. 

I am starting to fear tuition just because of her. Now when I enter my class, I have to be really careful, so that her sight doesn't catch me. She can be anywhere, waiting for me like a lion waiting for a deer in the grass. And she can strike at any moment from any direction. Yesterday, I just ran from my coaching centre to the bus stop, caught the first chinchi I saw and saved myself from her evil clutches. I attend my coaching classes in constant fear now. Allah saved me yesterday magar kab tak??? I am bound to be caught one day or another. OMG, save me, Im trapped :(.

Last night one of my friends started teasing me. She had seen that girl talking to me at Hibrow (thats the name of my coaching centre btw). I was teased in the following way:
I randomly asked my friend : "Wanna have a laddo??". She said: No, I would instead like to have a gulab jamun, of your wedding with that beaconhouse girl. You and her <3". I was like: OHHH NO NO NO NO!!!!!!!, never even say that again, please. Me and her, that would not be even a bit less than a nightmare". But she kept on teasing like both of you look good together and yaar is hi tarah tou larkiyan phasati hein larkon ko. I said: she called me "Bhai" so it proves that she is absolutely not after me. My friend said: there is nothing such as a brother-sister relationship between na mehrams, and that is the basic reason why na mehrams are called na mehrams. I said you're killing me but she kept teasing. I had to change the subject of our conversation to save myself from a stroke, brain hemorrhage or a really serious heart attack. 

GOD HAVE MERCY ON ME BECAUSE EVERY TIME I SEE HER NOW,I AM LIKE:

I might have exaggerated things a bit in the story above. but you don't know me, I am an stranger to you. So just take pleasure in my distress.
