Review Detail of RunnyWater in My Hidden Wife is Sweet

I dropped the story after the first fifteen chapters cause the whole thing where they were competing with their piano skills was just ridiculous. As someone who loves western classical music and has been playing the piano for ages, I just feel too offended to continue reading this story. I’ve seen stuff like this in so many other novels, like why can’t writers do proper research before writing or just stick with stuff they understand properly.
