How to pretend to chat casually with people you like?

If you are chatting online, if you are classmates or colleagues, and then encounter problems in your study or work, you can ask each other for help and advice to chat. In addition, if the temperature drops, you can send a message to the other party saying, "Keep warm, the weather will turn cold.". If rain is forecast, you can remind the other person to bring an umbrella or something, so that you can chat.

If it is in reality, you can ask each other directly when you encounter problems, and it is also possible to talk more, such as good movies and TV series, and then talk about your own heart.
