Hello there ts, i can give you some of hint when im giving one at potential mate.
Shy
Joke/laugh alot even if its awkward
will text you before bedtime
so on.
If you like a girl make her love you first before someone snatched her right infront of your eyes.

you can try by being funny as example. Buy her dinner, go watch Rom-Com at cinema.
Try switching personality each day meet her. If she likes one of the personality stay with it. If not better switch. As long as we dont find you out. You should be okey.
