Meera sitting here thinks about her life. She doesn't regret anything she does, she in her first life do a crime, but it will not happen if those people show her some humanity.
If in the start they offer her money for her kidney she might happily give it for her mother's treatment. But no, they have to fool her, use her.
And now about killing that man, she doesn't have any regret. She doesn't know which type of punishment she will get. she might never be able to go back to her life. But she doesn't feel much sadness. She lives two more lives very happily. She does her best for those whom she loves, and who love her. In this life too, she already does her best.
She is sure that Anuj will be okay and that he will take good care of Shivam. Chinu is safe. And Mahendra will defiantly take care of her mom. Talking about dad, that person is enough strong to take care of himself, it is just she doesn't get the chance to meet him.
