When it comes to misunderstandings the first novels that come to mind would be To Be a Power in the Shadows and I’m the Evil Lord of an Intergalactic Empire.
I'm really not the Demon God's Lackey It's a manhua Full of misunderstanding but not because the MC was ignorant, he just can't see what other people see
it has a novel too if i am correct https://www.novelupdates.com/series/im-really-not-the-demon-gods-lackey/ i will try it ^^ thank you~~~
