I'm a girl and I have a crush on this guy. I'm in school 5th grade. Here's how it works. Make sure あなた have post-its. When she または he is not looking grab the post it and pit your number on it. Don't put your name on it! Put it in his または her desk. Then when they see it make sure they don't know its you. Say that it is your friend. (Yes あなた have to lie.) Tell him または her not to call あなた just say to text. That is better off. If your name is in your voicemail change it. When he texts あなた say that is your friend. When you're ready ask him または her out. If they say no say how about some other time. Then continue from there. If they say yes then あなた should tell them who it really is. This happened to me and it worked he is dating someone else but I didn't ask him out yet. I'm have a plan. I hoped this helped!
