It's comedy. Period.

Every situation which is even a little bit dramatic or serious, instantly turns into comedy. Can't take anything of this even a little bit serious.

MC is as childish as her step children, even though she is a little bit older AND traveled 7 years back in time.
She continuously stoops low to the level of the kids, literally running after them. How did such a person even manage to survive and keep that household alive for 7 years?

The conversations are all meaningless and rushed. The author forcefully tries to be funny there, but it backfires completely. It's only annoying.

The plot is rushed as well. Conversations aren't even finished before the next "comedy" scene. Everything is made forcefully hectic. The characters are just screaming at each other for 80% of the plot.

Reading this far gave me a great headache ...
