Just my pov
Swara might remember her badi ma baba ragini n lakshya as a friend...that phase.
I dont think love between swa...lak will be shown ...as there was nothing like that...we all know.
Swara will not remember sanskar and sahil will enter as her saviour n friend... they will bond over music and sahil falling in love n turning obssessive for swara when he comes to know abt swasan.
Otherwise why will sahil turn obssessive if he doesnot have a competetor.
Sanskar will then try to get swara back by trying to bring back her memory.
Love triangle will start...i think acc to this article this should happen
Pari will help sahil...we know why
