After Transmigrating into a Book, I Became the Female Lead's Mother

This time travel book has one of the smoothest connections I have ever read. The heroine is not OOC, nor does she treat her children as an overly loving mother. She should be pretentious and squeamish when she should be, and she will not be coy when facing men. She does a long list of psychological construction, and has a strong ability to adapt to the environment, which is very good.

It's such a pity that the male protagonist retired from the army.
