The girl asked me to recharge her mobile phone. Do you want to recharge her?

You should fill it for her. After filling, there are two results. First, she accepted you, which shows that she has always liked you and didn't treat you like a fool or a nerd. She has been testing you. Second, she is using you, using your stupidity and nerdiness. If it is the first result, you will be very happy. If it is the second result, you can see her true face, so you will be cold to her and choose your love again. 100 yuan can test people's hearts, so why not?
