Contact directly by phone, WeChat or QQ, be proactive and diligent. When the time is right, ask her out to play (think of a good place) or go to the movies, and give you the number to promise you that it is an opportunity. Don't even think about it until I give it to you. That's a refusal ~ only you are direct ~ you can know what she means ~ Don't guess each other ~ If she comes out ~ It's obviously a chance for you ~ If she just doesn't come out ~ It means there is no intimacy ... Don't entangle, otherwise it will be counterproductive.
