Pretty sure there was this other manhwa withsimilar situation?
This other one story goes: zombie apocalypse. Seme keep went back in time with memories of the previous round intact. He keep trying to find out why he keep going back in time. Finally he found out that the Uke death was the key to the repeating timeline.
But everytime the Uke died and time repeat, Uke never remember anything. And that pissed Seme off.
Even when in couple of the timeline they both developed romantic and intimate relationships, when Uke died and time repeat, Uke forgot everything about Seme. Until we are back to chapter one (which is supposedly of many regressions) finally, Uke died and this time regression, Uke somehow remember the previous time.
But he still does not remember the countless regression of before.

This story just started! Although cliche, but not much is being told yet.
So I don't understand the low rating.
For me, this have good potential.
She was just a normal mom of 3, so of course she will not start as OP right away.
If people are upset because of how author make it that her 3 children was left behind and not sure what thier fate after, I'm sure author will reveal that later on when the story progress.
I don't think this story will have romance until later on when she aged up to her original age.
