I think it's because of the kids they shared, she was able to understand their language. Similar thing happened in the manga Red River( time travel)
I mean kiss *
Yes, I have the same hunch about it. In red river MC was kissed as well. Then she could understand the language after that
I meant an explanation for it.
Yeah, there could be those theories but it wasn't explained to the less knowledgable readers, especially since the scene shown that she woke up confused and was still unable to understand but just a few seconds page transition, she suddenly was able to, and even the characters herself didnt find it strange.
Yes, it'll be so confusing for them.
Unless they have read Red River where the same thing happened
What, the author didn't even put efforts to explain why she suddenly could understand their language? Like it wasn't the most emphasized thing in the first two chapters.
