once upon a girl

Surely you would agree that when you see someone dying, you should help him, right? , but from what I see , that this isn't the right thing to do, because after I did my heroic action, rushing into my neighbour's house after I saw him falling on the ground , coughing like he is ready to die , all I got was an angry boy yelling in my face like a crazy person
Meet Maya, She just moved out from her life in New York, to a new house with her 3years old brother and father
How will she adapt? And who is that boy and is she going to accept the deal with him? Is she going to help the people around her or she is going to ruin everything as always?
