Girls like romance and fantasy. Don't give her a very practical feeling and don't break her fantasy, otherwise you will have no chance at all.
Create a romantic and comfortable atmosphere for her, so that she has no pressure, and she will slowly lean towards you. Girls also like surprises. A small gift is very good, but it must make her feel very surprised.
So it is recommended to give a creative gift. I recommend a few to you:
Real dolls can be made into the style she likes. It is good to make them into constellations, which is enough to surprise her.
Starlight projector, a projector that can project starlight at night. Looking at the stars in the room at night is very romantic.
There are many other creative gifts. Go and see them in person. You will gain something. I hope it will be helpful to you.
