You read about someone you might like

You walk by someone who is a fair fit for what you read about someone you might like

You hear the voice of that someone and you like it

You like what the voice says

You find a way to share space and time with that someone, possibly in a group setting

You start daydreaming about what might happen

You present a better version of yourself in hopes the someone notices

You start accumulating nice moments involving your someone

You seem to notice a mutual attraction

You definitely notice a mutual attraction, unless your mind is playing tricks

Your heart leaps when one or the other of you throws caution to the winds and the two of you arrange to be together
