The ending point of the Tomo-chan anime in the manga can be a bit tricky to determine. Sometimes, the anime might condense or expand certain storylines compared to the manga. You might need to do a detailed comparison to figure it out precisely.

It could be about a girl with the nickname 'sweet cheeks' having various adventures in the world of 'Girl Meets World'.

Well, 'Fish Cheeks' isn't a novel. It could be a piece of creative non-fiction or a memoir perhaps. But it doesn't have the length and structure of a novel.
