I think the characters are set very nicely but I truly expected this to have more technical ping pong terms. Like haikyuu and many other sports mangas, technical terms of the sports are introduced quite often in the manga. Perhaps the manga is only at its introduction hence there isn’t much explanation. I’m looking forward to better explanation of the sport rather than just “Natsume Senpai is good at ping pong because his balls are fast” because that isn’t how ping pong works
