What should I do if I am disturbed by a villain? ..............

Draw a line with him, don't be too cold, but it's best not to be too enthusiastic. Because then he will depend on you in the future. Never have a property dispute with him. Enough is enough. Gradually alienate her {him} and not give him a look. If he is really a villain, he will definitely come for revenge. Because they usually have the illusion of persecution,
