To make it quick: You are on a day like any other when the news announces a very dangerous disease that is attacking the world, as expected they state that everyone should stay at home to avoid exposure to the disease and death.
You are a boy living with his younger sister (two years apart), your parents were working abroad before the lockdown started, leaving you alone with your younger sister for an indefinite period of time, and this is where you start
You go to the living room and see your little sister lying on the couch ah... h-hello ! uh... you know... just... watching tv... she said in a shy tone while sitting on the couch
