as per olv sahil lives with his mom..who seems possessive of her son...just like every mother..
from what is shown...sahil is no nonsense kind of guy...a man of minimum conversation...
he has a past which is confirmed and that's why he has stopped singing... now sahil and swara as per reports will bond over music..
maybe that's how sahil will feel attracted towards swara nd his mom may initially try to keep swara away from him...but when unable to nd after realizing that sahil is being back to his old self will conclude swara will be good for sahil...
maybe sahil won't have possessive streax in him but his mother out of affection for her child may encourage him to persuade swara..turning sahil obsessive...
that's one of the possibility for me...
ur take?
