I Photographed a Mysterious Cosplayer at a Convention, and She Turned Out to Be My Socially Anxious Neighbor

Any Stories About Cosplaying at Anime Conventions? No Transmigration, No Romance

Looking for books similar to Star Rail Livestream: The Streamer Can Cosplay Anything. No CP and no transmigration. I want a story about going to anime conventions and cosplaying, not one about transmigrating to another place. Thanks.
