Just another joke

I always admired this guy and for about a long time and sometimes thinking what would I do if he courts me and I just laugh at that thought, he would be crazy if he do that.
We are friends along with his other friends because they say that it's really easy to talk to me and tease me and pulling jokes at me without getting angry unlike the other girls in class. there's this one time 2 weeks before our Christmas break, I was getting bored in class and starts drawing at my book, then HE approached me. and said in a whisper,"hey, can you be my girlfriend?" I paused for a moment there and was like, in my thoughts."what? REALLY? it's like a dream come true" then I faced him & said "hhmmm?!" and eventually saw his other guy friends laughing behind us. so I think this is it, another joke and why would he even like me in the first place, I am just like a friend to him and so not his type. So I said,"right. suuurrre! why not?" because I think that's the only way to stop him. and then he was like "YEESSS! dude, I'm having a girfriend!" and throwing his arms up in the air like he win in some lottery. maybe they were betting on me or something. and I laugh because I didn't expect that. then he touched my right hand with his both hands. "love, you won't be regretting this". I was laughing and said "ok! just stop holding my hand!"
"why? you're my girlfriend now so I think this is just appropriate" and would not let go of my hand. maybe I should just say no in the first place?

then, some of my classmates noticed that were sitting close to each other at the same time holding hands. and I know they are about to tease me. "omg. look at that ! she just stole your crush from you tsk2!" and laughs. then the girl looked and said. "tsk2, I just turned my back from you and--- ahhh.! you! move a little farther from him! I said and giggled "ahh, sure, don't worry about it, this is just a joke hehe" when I was about to move my chair. he tugged my hand and said that only I can hear it,"don't. just don't mind them" with a serious face, looking down at my drawings. I just smiled at him and said "ok" then the girls keep teasing us. I said to him. "you should stop it know because they might get the wrong ideas and you would look bad on you crush" he replied smiling "hehe.. you don't even know my crush, and besides why should i? I'm having fun and you're my gf!" I simply replied "yeah.RIGHT" so that's it, he has a crush and still holding my hand.

oh. it keeps going until the christmas break. I sometimes tell myself.. it would really be nice if this were all true, and yet it's all just a joke. maybe this is how it feels to have a boyfriend , him to be my boyfriend, for a while. I know it was just another joke for him and his guy friend. but you know what I think... it's just a sweet memory he left with me and at the same time wounding, because I know I would always be just his friend.
