Review Detail of yuuuuuuuuki in Overlord, Love Me Tender

So this novel is just as cliché as every other novel but that's not necessarily a bad thing. It starts in the typical MC has been set up by two-faced sister scenario. We meet the ML in the beginning and it is exciting. The problem with this novel is the characters. The characters do a lot of things for no reason. Her brother just instantly submits to her with minimal effort. He is also described in such a confusing way that it is hard to tell if he is an enemy or ally at the start. The way the scumbag ex-fiancé just decides that he wants her back is too random and not satisfying at all. The biggest problem for me is the MC. Nothing about her is explained. We have no idea how she can do all the things she does. How is she so strong at the beginning? Her personality is just cringey to me. And also why does this random Mu guy help her at the Medicine Hall. It just makes zero sense. This novel is definitely not worth your time. There are other much better novels with more enjoyable characters and face-slapping.
