might be we are unable to understand her actions but she is good. She is the one who encouraged him for Ak and time and again asked for Ak well being when none of her family asked it. They definitely have that bonding. Today too she is shown realising is it like How I made Abhi agree for Arohi, Ak is doing for Arohi ?she got the right question at last .
What may happen in the future , I don't know , but manjaris character is one who is put down by her husband and mahima every minute ..anything she says , they call her dimwit ... That's the reason abhimanyu tries to respect her wish , to keep her word..she is not sly or innocent ..she is actually a dimwit woman ..but if someone is like that , they don't lose the right to live in this world.
