I’m having trouble understanding the bolded part. I’m so unsure of even the pieces (seems like it’s very contextual) that I’m not going to break it down myself.
The first part of the bolded text means “Even if I [Fey] told someone [about it] they wouldn’t/didn’t understand”, and the second part points to the previous sentence and means something like “[the fact that Lutz] knows how to «deal with» [the angry Myne] makes me feel a bit relieved”.
Thanks, that makes sense! Also, where is every getting these not-standard romanizations to spell the names? Is that how the anime spells them or something?
“Even if I told someone, they wouldn’t get it, so… [now that] I know how to deal with her / what to do, it’s somewhat of a relief / I can breathe more easily.”
I liked these two short stories. Are you sure there is 30 pages in total this week? It felt so short. It’s the first time I read it in one go. I was sure they were 3 stories.
Short story 1
The first story was nice to give more background and details about characters other than Mayne. The hunting 魔獣 was kinda scaring me but as long as the 魔獣 is not a rabbit everything should be good. The hunting of the 魔獣 was interesting. Kinda gore at one part but interesting. We can see how for them something normal is not. I like how that world is making something normal something that is not for us. The name of fruits and animals does get hard to remember thought Lutz brother are getting less and less likable by the time.
Short story 2
That story was harder to understand but I managed. It was so cute. Mayne really could use some surrounding awareness. How can you not realize when all light goes down. Then she gets stuck more than once in a library after closure. I’m happy at least 修 was able to have fun at the planetarium. I share his despair with Urano. When I am doing a trip or shopping, I like to go into a book shop but not ONLY doing that. I was thinking maybe I’m passing too much time in book shop just looking around. Looks like I was weak-minded.
I will be hoping to read next volume with you guys
Haven’t watched the anime yet
