Registered friends linked to the platform cannot be deleted, so it is limited in implementing the system we want. Also, although this function varies depending on the platform, it is a system that is registered only by disclosing a list of friends on the steam platform. That's why it's very difficult to manage your friend list. In addition, it is true that users who play our game have a lot of inconvenience in using it.
Considering these points, please review our request.
