Mata on gangur said whose evil eyes fell on ar. In real its ar ka evil eyes fell on ak happiness which had always been her problem since childhood.
Till aarohi doesn't know the truth she was happy in her world. The moment she learnt abhir truth saw abhir abhi bond she understood the unsaid love and happiness of both abhira in the form of abhir. How abhi even without knowing truth is on abhir. The love abhi shows towards abhir is the same love he has for ak which literally threatened aarohi and her life.
The first time after she learnt abhir truth aarohi eyed abhir abhi bond and kid immediately coughed.
The second time in hospital she saw abhi happiness to meet abhir and sent him away and kid immediately got bp fluctuations and can't breath.
Now thrid time today she said about abhir abhi bond and immediately machines caught fire and kid was in danger.
This is the same aarohi since childhood can't bear ak happiness anyday next it turned to abhira happiness where she promised and openly challenged abhi to snatch away all their happiness. She successfully did it through her widow victim card threw ak as nothing and royally enjoyed her life.
Ak on ar birthday gifted a hair clip with 6 hearts. Told how she liked such things since childhood. Which shows how she is holding ak abhi abhir nav herself and ruhi all 6 lives in her selfishness and obsession.
