As an old college graduate, I can tell you that if you meet a boy you like, you must take the initiative and seize the time, otherwise you will really regret it.
First, get to know the classmates and friends around him. As the saying goes: Those who are close to red are red and those who are close to ink are black. If his friend's conduct is upright and his character is excellent, his character will definitely not be any worse. Getting to know his friends and his circle of friends will help you gain a more comprehensive understanding of the person you like, as well as his personality traits, living habits, etc. Of course, the most important thing is to ask clearly whether he has a girlfriend and whether you have any competitors. There must be no ambiguity about these two things.
Second, choose to appear where he often appears. If he likes to study in the library, then find a seat opposite him. If he likes to play table tennis, tell him that you are also interested and can ask him to teach you. The main purpose of doing this is to increase your sense of presence, let him know that you are actually different from him, and let him realize that you actually like him. Of course, if he is not repelled by these behaviors or has even gradually become accustomed to them or wants to take the initiative to date you, then congratulations, a good start is half the battle, and you have already walked half the journey. Of course, if he hates this kind of behavior, then stop it as soon as possible.
Third, when you radiate your personal charm, you don’t need to cater to him too deliberately, because this will appear unnatural and put you in a particularly passive position. You just need to maintain yourself in front of him and be more polite. Just add a little bit of modification. Whatever is suitable will be suitable after all. This can help you get to know each other faster and understand each other, so let your charm shine, little girl.
