I think it's a sequel only because it's based on S&S daughter's story. Implicitly some characters of this show or other elements (music, happenings, related facts) are brought in.
Also, like in DABH, the story is about how two opposite human natures meet, have to live together, fight till fall in love (no needs in the same time).Than they learn to adjust and respect each other's individuality, discover the other's qualities, love and trust grows up and they become inseparable.
But it doesn't have to be a similar story, two stories of life/ love are rarely alike.
Even Kanak doesn't need to be like her parents. One's temper could be alike to his parents'/ relatives', but conditions of his growing up or his upbringing put their mark on anyone's personality.
As the story make progress i am sure it will be more related with DABH, Kanak will make honor to her parents and to her family, too.
Just let's have patience.
