This is my Five minute five-minute speech script part 1. Please help me correct the errors.

I'm not good at in English, so I really need your help.
Only some parts of it will be very thankful! okay.

Hello, everyone! I think most of you know my name but some of you may not know me, so I think I should introduce myself. My name is 박진영, 22 years old. I like to listen to rock music. But I also like pops. Jazz, blues… many other kinds of music, so feel free to talk to me. And I really love to drink, so if anyone loves to drink like me, call me anytime. I’ll wait your contact.

Hello, everyone! I think most of you know my name but for those who don't, please allow me to introduce myself. My name is 박진영 and I am 22 years old. I like to listen to a lot of music genre like rock, pop, jazz, and blues. (If rock is your favourite music, you may say, "I really like rock music a lot, but I also listen to other genre like pop, jazz, and blues.) I also enjoy drinking (better if you say "with my friends." I don't think it's nice to be open to strangers for a drinking session. Unless you're talking to your friends here. But it's up to you.)

Then, let’s begin.

Do you have a good summer vacation? Well, I don’t. All plans that I planned before summer break had been blown to the air. Study hard, Do exercise, Read books etc… all was gone except just one thing. That is, ‘Take a trip to Haeundae’.

Did you have a good summer vacation? Well, I didn't. All my plans were have been gone to waste - study hard, exercise, and read books - except for one, which was ‘Take a trip to Haeundae.’

To make the last one came true, I and my friends make a week-long trip plan. At that time, we were so exciting because of the expectation that we make a plan with passionate manners. But, more and more the time to leave drew near, more and more problems arose. Original members were eight, but three of them were left out because of their own reasons. One of them had an veery embarrassing reason. His grandfather had passed away just before the one night we planned to leave. Anyway, because of these situations, I had a sudden sinking feeling when I departed.

To make it happen, my friends and I had to make a week-long plan. We were really excited about it. We even imagined how our trip would be. (I'm making a complete revision here, for simplicity's sake.) However, as the time for the trip came closer, the more problem we had to face. There were originally eight of us for this trip, but three of our friends backed out because of personal reasons. (Do you mean the person whose grandfather passed away was the one with an embarassing reason? If so, it's actually not embarassing but rather sad. You may not mention any of their reason. If you still want to, you may say, "One of them had his grandfather passed away.") Because of the situation, I had a sudden feeling of being left behind.

But, When I arrived Haeundae, Haeundae’s strong sunlight and cheerful atmosphere had melt my all blue feelings. I and my friends had a really good time there. We ate many super-delicious foods, we drank lots bottles of Soju, Vodka and Kahlua and swimming in the sea whenever we wanted. Sadly, two handsome friends could not join our trip so we couldn’t have conversation with someone of the opposite sex. Except for this, that was the greatest trip I ever took with friends.

We still went to Haeundae though. As soon we arrived, it seemed like all my sadness had been melted by the beautiful place and the sunlight. My friends and I really had a great time. We ate a lot of delicious foods and had some drinking sessions of soju, vodka, and kahlua. We also went swimming whenever we wanted. It was unfortunate that two of our male friends were not able to join us. There was no one from the opposite sex to talk to. However, it was still the greatest trip I've had with my friends.

And, because I enjoyed too much there, one problem had been occur. That was, I forgot to reserve the bust ticket which was planned to leave on Sunday. When I went to the ticket office on Sunday, I heard the shocking news. There was no ticket left, even the late-night bus ticket. So, I had no choice but to book a bus ticket which was leaving at 12:30 p.m. the next day. Because of this, I couldn’t attend the whole classes on Monday.

Because I was having so much fun, I forgot to make reservations for our Sunday trip back home. When I went to the ticket booth on Sunday, I was told that there was no more available ticket, not even for a late-night trip. I had no choice but to make reservations for the 12:30 trip the next day. Because of what happened, I wasn't able to attend my classes on Monday.

I hope this helps. =)
