I just finished reading ch1 as fast as I could without skipping pages, it was awful. It's the Otaku genre/trope codified. It managed to hit every single trope/stereotype note and no others.
MC dedicated to the Otaku category and holding onto and uses something really old and useless. Despite that, doing good with it.
MC being a dark horse underdog who has reasons we can expect him to reach excellence yet somehow is unknown.
MC excelling in a very peculiar and specialized way, with a weakness built in but strength that just pushes past said weakness.
MC is male.
Arrogant female Otaku challenges MC to a match sure she will win. Loses and develops respect for MC and becomes a quasi love interest that doesn't go anywhere.
Otaku category heavily glorified to sickening levels. You can be sure Ping pong will be the only thing the plot and every other part of the comic, will care about.
I also put this in comments, but since I don't plan to read this again, I won't know if people respond. But if they reply to this, I will know.
