Review Detail of JustOldLaundry in I Transmigrate as a Single Mother of the Three Antagonists

Pretty horrible because it just revolves around the kids being mad and acting far too mature for a 6 year old. The MC is just a regular basically OP mom with 3 hateful kids a good nice one. Still can’t process how one of them knowa chemistry to the point where he can develop a drug and the girl can hack. Where, how, who taught them?
