How does Tik Tok humorously ask for WeChat?

Tik Tok's humorous WeChat is as follows:

1, hello, I think our conversation is very enjoyable. If I continue, I may need your WeChat for further communication. Excuse me, can I use your WeChat?

I found an interesting rule. As long as I talk to you for more than three sentences, I will want to add your WeChat. Is this a superpower? Can you tell me your WeChat?

3. I heard that smart people will leave their own micro-signals. So, what's your micro signal? I promise not to show off that I know you to others.
