When the relationship is closer, you can try to pay more attention to her language, such as sending text messages to remind her to bring an umbrella when it is cloudy (she probably remembers it when it is sunny). You can also pay attention to the weather forecast and tell her to wear more clothes when it is cold, drink more water when it is hot, and pay attention to the changes of seasons. Tell jokes when she is unhappy, buy delicious food and make her happy when she is happy. She said some true words to encourage her to go through all the previous brewing, and finally you can find a suitable time to express your courage, such as a sunny morning, a warm afternoon and a quiet starry night. In fact, the time requirement is not very high, just feel right. You can't give up your concern and care for her after your confession is successful. Be kind to her. Of course, there is no absolute thing in the world. Although you have done well in the front, you may still fail. If you fail, don't lose heart. Stick to it for a while and you will be rejected. Then look forward optimistically and find the next girl who makes you feel excited.
