When a female colleague likes you but restrains her feelings, she may show some of the following signs:
1.*Frequent eye contact**: She may look at you a lot, but quickly shifts her gaze when you spot it, as if restraining herself from being detected.
2.*Attention to you**: She may show special attention to your work, life, or interests, often asking about you.
3.*Social interaction**: She may interact more with you at work or at team activities, but not too overtly or proactively.
4.*Body Language**: Her body language may reveal some signs of nervousness or unnaturalness, such as fiddling with her hair, fingers crossed, etc.
5.*Avoid too close contact**: Although she may have a crush on you, she will restrain herself from having too much physical contact with you and keep a certain distance.
6.*Topic Choice**: When communicating with you, she may choose something more general or work-related and avoid personal feelings.
7.*Gifts or small gestures**: She may give you small gifts or do small gestures of caring for you once in a while, but not too conspicuously.
8.*Perform better in front of you**: She may strive to put her best foot forward in front of you, such as paying more attention to her image or work performance.
9.Social: She may have some interaction with you on social, but not too often or too intimately.
10.*Refrain from expressing your emotions**: She may try to restrain her emotional expressions towards you and not reveal her thoughts easily.
It's important to note that these performances don't necessarily mean that female colleagues necessarily like you, and everyone may behave and express differently. In addition, it is important to respect her feelings and boundaries and not to over-read her actions. If you also have a crush on her, you can increase communication with her in an appropriate way to better understand her thoughts. But also take care to maintain professional and appropriate behavior in the workplace. If you are uncertain or not interested in her feelings, it is best to maintain a friendly and respectful attitude and avoid giving her the wrong signals or causing unnecessary distress.
