2. Borrow something from her on purpose, or use other excuses to increase the chances of communication and talk, so that he can know more about you and deepen his feelings.
3. After getting closer, ask her out to play, and you can give her a small gift when you go out to play. She will know that you like her, and she will gradually feel it in her heart.
4. When you think she has feelings for you, find another opportunity to tell her, and then she will refuse.
It's normal to refuse. Even if you like it, you will be rejected 1 or twice, otherwise women will feel "very cheap".
6. Don't worry after refusing, deliberately ignore her for a few days, then continue to ask her out, and then continue to confess, just a few more times, and she agreed.
I wish you success!
