Someone put in the effort to upload this. With a grateful heart, I opened it and confirmed that the Brad with the nickname I applied for is wandering somewhere in the World Stage.

For those who were disappointed with the quality of the World Stage like me and haven't touched it, it seems not bad to use it to check if the nickname you applied for is included.

There are more Korean nicknames than I thought.
