First of all, boys should be confident at all times. Before some boys catch up with others, girls become timid and seem to have no confidence. The reason why boys are afraid to make moves is because they are afraid of being rejected by girls and losing face. In fact, you should bravely pursue love during college, and you can secretly love in high school. If the university still has a secret crush, it will be boring. For a girl who pursues her heart, even if she is rejected, it is not a shameful thing.
Secondly, we should make ourselves excellent in college. The reason why girls reject you may be because of your looks or because you are not good enough. Most girls like excellent boys, so making themselves excellent in college will also help to change their image in girls' minds. For example, when going out, be sure to pay attention to cleanliness. Keep a positive attitude in everything you do. In fact, these little details in life will become reasons to attract others.
Also, look at the girl's hint. Whether girls like you or not can be seen through some details. Many girls are too shy to say what they want to say directly. At this time, boys must be smart and understand the hints of girls. Some girls don't say what they think, but body language doesn't lie. If a boy can understand a girl's body language, it will be easier to catch up with his goddess.
