Article in English: Think about whether your coworker compliments you a lot. Compliments or other positive remarks might indicate that they have a high opinion of you or even a crush on you.  If your coworker consistently compliments the job you’re doing at work, it might mean that they just respect you as a coworker. If your coworker compliments your physical looks or other things that are not related to work, it might mean that they have romantic interest in you. Don’t take compliments by themselves as an indication of your coworker having a crush. Evaluate compliments in the context of other factors. The subject of your conversations with your coworker can give you pretty solid cues about their feelings for you. As a result, pay a little attention to what your coworker says to you and the types of conversations they initiate. Ask yourself:  Does your coworker bring up highly personal information?  If so, this might signal that they see you as more than just an acquaintance. Does your coworker talk sex, being intimate, or romantic interests? This might be a way of getting your attention in a romantic way. Does your coworker confide in you? This suggests that they see you as more than just a coworker. Does your coworker invite you to activities outside of work? This could be a sure sign they’re interested in you romantically. After watching for other signals, you might just need to plain out ask your coworker if they have a crush on you. While this might not be the easiest or the most comfortable thing to do, it may get the results you want.  Say something like “do you think our relationship goes beyond work?” If you don’t want to be direct, try using humor to offset your question. Perhaps make a joke about how other employees avoid you, then say “you don’t seem to hate me like everyone else.” Be careful about suggesting you want more than a work relationship.
