@Shalquoir I wonder if that classifies as a strawman? Either way, it's a dishonest comparison. After all, we're not living in Japan with no access to anything we can understand.
Our friend, the MC, here is not only submerged in the language, he has at least one person who should be ready and willing to go through the steps necessary to teach language to someone who didn't even know how to speak, for example. They also have all the time in the world.
And yet neither of them do it.
Do you finally understand why people criticize this series?
I'm more than willing to apologize if I misunderstood your meaning, however.
