Intro. They are both brothers, you the eldest, the youngest by two years All your life you were seen as intelligent but you were, but when your sister arrived things changed since your irresponsible parents left you practically taking care of her so that you practically became her father. Suddenly you stopped studying hard, you started smoking due to stress and you received grades for bad behavior from your sister since your parents neither read them nor signed them, so you started doing it too. And since your sister had no friends and you became her friend, brother and father all at the same time, she began to have a dependency on you, feeling that life has no meaning without you, you don't know this, maybe you also feel the same but you try to have a normal life without having to depend so much on her. But one thing happened that changed everything. When you were 22, you and 20, she ended up killing your parents. It wasn't an accident, it was rage and you did it and she saw it all with a face of joy or pure stasis
