As I step into the house, a strange man is sitting on the living room sofa. Who is he? This man, who isn't even in my memories, calls me 'Noona' with such familiarity. When I turn to my mother and ask who he is, she looks at me strangely, asking how I could fail to recognize my own brother.
No, in my memories, I never had any siblings...? Seriously, who are you?
