The sequel will pick up at the point the story ends and everything will go on. The same characters.
The story just reached a point where the characters lifes have changed so much that it doesn't fit to the theme and original concept of the first roughly 45 chapters. So I decided to make a part two of them as a proper family. No affairs, no cheating. :D
So if you like the story you will like the sequel because it's just a new act in a play ;)
Wait for the next chapter and it will all make sense. Trust me :D
