First, since high school students must have contact information, there will be no embarrassment in contacting as old classmates;

Second, girls are more psychologically mature than boys. They haven't been in touch for a long time. It is impossible to ask when they first contacted her. To say the least, even if you ask, you can say that you knew nothing about love when you were young. You can also say that you actually liked it, but you were too thin to admit it.

Third, have a purpose, a clear purpose, that is, like her and want her to be your girlfriend. Do girls want to be with anyone who casually asks her to play?

Fourth, learn about her hobbies, food and gameplay from the front and side, then talk to her more about what she is interested in, buy snacks she likes to eat, and eat her favorite dishes together, and gradually she will believe it;

Finally, it is said that the relationship has been enhanced. If you haven't reached this point with her, get in touch with him slowly and talk about some interesting things in high school. Remember not to be stingy with praise and not to spend money indiscriminately. Praise what girls like generously and appropriately. Wish you success!
