What does it mean when a friend of the opposite sex uses my photo as a chat background?

If a friend of the opposite sex uses your photo as the chat background, there is a situation where he sets the chat background of everyone in his chat software to your photo. So the first possibility is that he simply thinks you are good-looking, or at least that photo looks good to him, so he thinks it is pleasing to set your photo as the background of all chats, a bit similar to how we use your favorite celebrities or Picture set as chat background. However, this situation is more likely to develop into him liking you, because he has begun to appreciate your beauty. If you like him, the success rate of pursuing you is also very high, so you can act boldly! If you don't have feelings for him, just think of him as having a little fanboy who affirms your appearance.

Another situation is that there is really nothing special about this situation. He just sets the background of the chat with you to your photo, and the background of the chat with other people is other people’s photos. He just has this habit of setting the chat partner as the chat background. However, this does not mean that he is not interested in you. He may also be a reserved person. He likes you but may not express it. So, if you like him, you can still try to flirt with him~ Women chase men with separate layers of gauze. But if you're not interested in him, you don't have to worry about it.

However, I guess that if you ask this question, you either have a slight liking for this friend of the opposite sex, or you think of him as your best friend, brother or best friend, and you are worried that the other person likes you, and then you are afraid that if you reject him, you will have no friends. All in all, I hope my answer is helpful to you. Come on, you can definitely handle it!
