Is this manga good?
So many people seem to like it, but when I read a few chapters (A long time ago) the protagonist and the prince (If I remember right, he didn't appear but he didn't like his wife to meet with her because of jealousy. WTF!?) and the protagonist seemed annoying too
is it good? Does it get better? Is she annoying or not? Like motherly annoying like it seemed, self-centred, "I am always right", "You are wrong. I am never wrong", never apologises?

Note: I am not insulting the manga in any ways, okay? I know some people may get my words the wrong way or just wanna pick a fight, but I just wanna know if its worth the read. I just really like Isekai, but I think that some authors goes way too far in the "bad" characteristics of some characters and don't make them grow up.
I liked stuff like In this reincarnation I will find happiness!!, The death bound duke's daughter (the novel is much, MUCH better. Don't judge her by the manga. Trust me. Unfortunately it's on hiatus :(. Also, the art doesn't match the novel. Like, totally doesn't), The villainess wants to marry a commoner, Miniature Garden Chemistry, the one about princess Mia that I forgot the name. I bought the first two novels and they are totally worth the read! You laugh and laugh. The english translation is phenomenal :)
