I added a female colleague's WeChat and didn't reply to my message. I didn't talk when I met the next day, as if I were avoiding me. I didn't chase her. What happened?

If you add a female colleague's WeChat, and then you send him a message, he doesn't return, and he doesn't talk to you when he meets the next day, as if he has been avoiding you. Although you said you didn't think you were chasing her, he reacted like this. In fact, he knows in his heart that you added him to chase her. Although you said you didn't show it, he could guess. So he is not interested in you, and he doesn't want to be chased by you. He thinks you added him because of work. Who knows you have wild desires for him? He simply avoids you.
