So It's not the translation

I was trying to give this the benefit of the doubt and say that the translation was the problem but the actual plot is so rushed nothing makes sense. It feels like this story started 30 chaps in and we just have to assume a bunch of background knowledge of the mc and ml and why they are even together in the beginning. But I'm dropping it at this point since the clarification is barely there. ╮(￣▽￣)╭
