I don't know why but a crazy thought went through my head what if crazy scientist is the dad. I mean the children are basically clones of mom, and the quintuplets are for control group and different modification types.
I need to create my own dark drama for such wholesome manga.
The little ones were quintuplets.
Before them, two more sisters.
Before them, Effa.
Then I saw the mother and understood that she had the assets. Enlightened.
This is such a happy-go-lucky series that it washes away all of the series’ problems. The predictability and occasional flaw in the story’s logic don’t matter one bit, it’s too fluffy and optimistic to hate!
