Review Detail of Shiki in Obtaining 10x rewards! Reincarnated into a novel as a side-character!

Too much forced plot and repeatings, plus author appearently doesn't care about what he wrote a few chapters prior and constantly changes things like how at the beginning he says the mc is born a few days after his sister but 10 chap later it turns to weeks after, and this is not the only time something like this happens. All these things just breaks the flow of the story causing readers to quit.
