Q. Tell me about the friend feature.

A. The friend function is accessible through the top-right corner of the main game screen. Please refer to the details below.

- If you send or accept a friend request, you become friends with each other.

- You can register up to 40 friends.

- If you block a friend, they will be immediately removed from your friend list, and you will not receive any friend requests from them.

- Even if you unblock a friend, they won't appear in your friend list, and you need to re-register them as a friend.
