What will you do to make a girl like a guy?

Just be yourself

You can't. A girl might like you if you're really nice to her and treat her nicely, but you can't MAKE a girl like you. It's a free will thing and nobody can change that but the girl. However, if you treat her nicely and respect her then she might like you.

DON'T grovel at her feet and offer her chocolates every day, and definitely DO NOT stalk her. Trust me, speaking as a girl there is nothing that puts you off more than a stalker. Just be friendly and nice but don't be clingy, and don't give up the rest of your life just for one girl who might not turn out to be worth it.
