“Sorry, papa. I am feeling very, very alone” — these were the final words of three sisters who died by suicide after jumping from the ninth floor of their residential building in Uttar Pradesh's Ghaziabad. The incident took place around 2 am on Wednesday.

Pakhi (12), Prachi (14), and Vishika (16) were allegedly obsessed with an online Korean task-based game that is being linked to their suicide. 

In the dead of night, the sisters went to their balcony, bolted the door and jumped out of a window, one after the other. Their screams and the sound of the bodies hitting the ground were loud enough to wake their parents, neighbours and security guards at the apartment complex at Bharat City in Ghaziabad. By the time the parents broke open the door to the balcony, it was too late.

The sisters were addicted to a "Korean love game", so much in fact, that they did hardly anything else. They had reportedly stopped going to school two years ago.

Investigations are focusing on their suicide note and a diary they cited in it. A note was found in the victims' room, with a crying emoji, which read, "A true life story. Is diary mein jo kuch bhi likha hain, woh sab padh lo, kyunki ye sab sach hain. (Whatever you are seeing in this diary, read everything, because everything is true) Read now! I am really sorry, sorry papa."

Police are yet to confirm whether the suicide is linked to online gaming addiction and said the exact reason behind the deaths is still unclear.
