Wtf? So the author decided, yes, the imouto has some conscience left afterall (or she decided grooming her nephew is easier).
Afterwards, just time skip to about a decade in the future regardless.
The storytelling is getting really haphazard. I mean the story pace of our MC making and raising his kids is just as fast as his skill learning speed.
His relationship with his wife (and also with most other people) is also largely untouched.
Our MC met with so many people in his journey and yet there’s…. nothing the author can use to make an interesting plot instead of just timeskipping….
This really makes it hard to care much about the characters in the series.
