I did first club game few days before.
I watched all Keys to Vip seasons so ...

Me) - Hi, what's your name ?
HB7 - ...
Me) - my name is ... nice to meet you.
Me) - Actually the reason why i came to say hi to you is that i have seen your before 5 minutes, and i think you most the beatifull girl in the club.
HB7) - Smiling
Me) - how would rate my looks from 1 to 10
HB7) - 9
Me ) - Well, i will give you 9,5 i like your t-hsirt, i like your necklace, but i dont like your jeans, it's too dark.
Me ) - Where you from ?
HB7) - ....
Me ) It's my favourite city ... High five .

HB7) - ( My name) , do you came with friend ? ( She came with friend )
Me )- Yes, but he's smoking or something like this.
Me ) - I will back soon, i have to find my friend.
HB7) - Ok

Came with friend, when she was with friend, but my friend has no game and no style, he thinks that Keys to vip is Fake show

He asked do you want to dance.I didn't see interest to my friend and me i first left target.

Later i didn't ask number, so i don't know i did my approach ok or not.

You did a good job with the approach but you didnt finish it. You coul have just asked her for the nuber before you went to find your friend and thats it. Or you could have gone dancing with her, touch her on the dance flore and make out.
