Please Help Me~I Got Some Problems

I think you need to use your conversation time to extract information from her. From her personal details (family, friends) to her interests, you need to come up with a plan.
After knowing her, you need to first see whether you have something in common with her. Then you can suggest doing those things with her (movies, walking on the beach, etc). Also tell her something unique about yourself in the process. Most important thing is make your conversation interesting, praise her a lot. That is what I found to be a very effective tool.
Then it is really up to her whether she likes you or not. If she is, as you said, rich and beautiful and smart, then you would have to expect that many boys will be after her. Stay close to her and be a friend, then wait for the right moment.
Good Luck to you and feel free to ask me further.
Hope it helps.

Simple: when you are all together, tell her you want to ask her something and pull her aside. Then ask her something unimportant, then after she answered you said "by the way, would you have time for such and such"Should work if she likes you.

um... 女仔鍾意男仔gentleman d 同埋大方d, 唔好婆婆媽媽, 唔好自卑, 有自信d, 但又唔可以擺一個驕傲既款!!
gentleman d 就係幫佢拎下野, 推門, 溫柔d呀! 大方就係唔好斤斤計較啦... 唔好咁姑寒...
講多d笑, 但唔好太白痴呀! 唔好太好花花, 適可而止!!
