In the flight, Athira was teary eyed, murmuring to a photo with her parents and Druvi in her phone.
In the flashback, it was revealed that Athira was daughter of Druvi's paternal uncle and adopted by Druvi's parents after their death in an accident.
Druvi got more attention, love and care than Athira, still Athiva didn't complained about this. Years later, Athira went for her police training.
After completing her training, she heard about her adoptives murder from neighbours.
Athira was confused because Druvi didn't her informed about this.
She went to met Druvi's new home where she shifted after her parents death.
On the stormy night, she went to Druvi and asked that why she didn't informed her about her parents death.
Being forced, Druvi revealed that she killed her parents with the help of Sreenu as they're against her and Sreenu's relations.
On hearing this, Athira killed Druvi with a pen, which Druvi's maid witnessed. Athira hitted the maid with a vase. While clearing all mess, she heard someone's footstep coming towards the home.
To save herself, she went outside wearing a dark raincoat over the garden wall, which was seen by Sreenu.
He couldn't stopped her and was not sure who was it, as it's dark.
Sreenu felt destroyed when he saw Druvi as dead.
In hospital, Athira got a call about maid's consciousness before Vishwa and reached before her team and killed the her. When the team reached with Vishwa and saw Athira's enter and exit footage in cctv, Vishwa got to know that Athira was the murderer of Druvi.
Unfortunately, she boarded her flight with Druvi's son, before all before they catch her.
In present, Athira kissed on Druvi's son's forehead while he's sleeping beside her. And remembering her parents by heart.
As she's going to start her new life in a new place.
