Wechat sent a lot of messages to female colleagues, and none of them returned. What do you mean?

Probably because she has a boyfriend. The reason why she doesn't want to see you is that she feels harassed. Personally, I think it is better to give up. Now that she has a boyfriend, bless her! Even if you really chase her, if she chooses another one when she has a boyfriend, the girl of this person believes that it is not good to give it to others! If you offend your personal opinion, you will get cold!
