There is no content about the opposite sex in the circle of friends, and there is no such thing as taking love photos on Valentine's Day on Tanabata. Is such a girl likely to be single?

This is divided into general cases and special cases.

Generally speaking, the probability of being single is high, because girls feel happy and like to show it to their friends. However, now that the circle of friends has a blocking function, you have to find out whether it is blocked.

The special situation is that the working environment is not allowed to fall in love and dare not bask in it. Another possibility is that you are still in love and choosing not to bask in the sun.

If you want to know whether she is single, you can ask directly. You can also get to know her by contacting her friends.

Actually, don't make it so complicated, just chase it. If you are not single, tell her that you like her!
