Since my day one

Two sisters who have each other's back but does that mean they know everything about each other? Even the pain they hide from each other. Mansi has always been the one who is understanding but does that mean anyone understands her? A happy marriage and a profession everyone dreams of means she is happy. She is selfless does that mean she doesn’t want anything? Manvi has always been the one who speaks what she wants. Does that mean she is not hiding anything? She has the freedom she always dreamt of in childhood. But is she satisfied? She Laughs all the time, Does that mean she is happy?
