1. Like you
She keeps her distance from other boys, but it's natural that she likes you so much. Let you bring breakfast again, that is, enter the "couple stage" in advance! Of course, bringing breakfast is not entirely certain. You can think of some other way to try again. For example, if she asks you to bring breakfast, you can ask her to help you wash the dishes. If she wants to, it means that she really likes you.
2. Waste testing
In the emotional world, there is a word called "waste test". To put it bluntly, it is to put forward some requirements to test whether the other party has value and mentality. According to your description, it is very likely that girls are giving you this kind of test and will consider whether to associate with you according to the test results. The good news is that you are on the waiting list, and the bad news is that you may queue up on the waiting list, but queuing means hope, showing your charm and still attracting her.
3. It's her personality.
Some people are born to be spoiled, some people are born to be leaders, and some people are born to like others to help her. If they know what they can do, they will ask others for help. This is the reason for the woman's character! Don't be surprised. In fact, there are many such people in our lives. After all, "everyone has a lazy heart." Of course you can't do anything that can help others! So, if she has this personality, then she may not only let you bring food alone, but also A, B, C, D and so on.
4. Your personality makes it.
There are people who like to help others, and naturally there are people who like to help others. When I was in high school, I especially liked to help people buy things, or recommend others to buy things, because every time I helped others, I felt very fulfilled and excited all day. If I follow the logic of "a female colleague wants me to bring breakfast, and she likes me", then I may be liked by the whole class! This is naturally unrealistic. They want me to bring things, which has little to do with whether they like me or not, but I have good resources in my hand. Similarly, a female colleague asked you to bring food, probably because she thought you could cook and like to help others, so she casually mentioned it.
Look, there are many possibilities for a small request. It is not easy to make an accurate judgment, and more observation is needed. Just like a detective solving a case, it needs to be analyzed according to all the information, and it is not easy to draw conclusions only by relying on superficial relationships.
