Who?

Reality

It was still raining outside, Robin brought his car keys and asked Noah to follow him. 'We shall go to meet Dr. Kim Woojin, He is a great person, only he can help us in such a situation.'
Noah followed Robin, he was the only person alive whom Noah could trust. They went to his garage, Robin's Jaguar was parked, but they went beside it and sat in the usual ride, Dodge Challenger 1970, Robin's favourite out of all his 23 cars. He used to ride Jaguar and others only when he was expecting a formal guest, he always rode Challenger when he was with his friends. 'She is beautiful, isn't she, the red colour suits her body well, she looked cute in green but she looks hot in red.' He said referring to his car, or his Linda as he used to call her, it was his Father's car but he was gifted that car on his graduation, renovated with all modern features. 'She looks as sexy as always.' Noah said smiling. He was smiling after a long time.
They made their way to Dr. Woojin's home, listening to Queen and The Beatles as always.
They got off at 12 Park Street, a modest house. There was a big board in the front which said, Beware Of Dogs. On the left there was the nameplate- Dr. Woojin Kim, professor of History at Princely University Of Victoria. There was one end of the intercom system above the nameplate. 'Quite posh for a modest house', Noah thought. 'Professor Woojin, It's me Robin Wilson, I have Noah Godson with me. We need your help immediately, please let us in sir.' The gate opened at that very instant. Noah followed Robin inside, there were lines of dog houses on both sides of the path to the house, at least 12 dogs were there. Noah was surprised. There was a Rolls Royce parked in the shed. Noah was utterly bewildered. 'Don't be worried, it's just his temporary house, he keeps changing Universities, he teaches on Semester basis, he used to teach in Oxford before this.
As soon as they entered the house, Noah was left bewildered. The house was nothing of what a person might expect from outside, it was as big as his ancestral house. 'Don't be so surprised, I like to maintain a low profile in public eyes.' A strong and stiff voice said from the top of the stairs, dressed in his sleeping robe, Dr. Woojin, appeared. His face was strict, he looked better than Robin or Noah himself, nobody would think that he is a professor from his young appearance. He looked as if he were in his early 20s, but in reality he was in his 50s. He asked them to sit. He came and sat across to Robin and Noah. His face appeared vaguely familiar, as if Noah had seen him multiple times but he couldn't recognise him.
Robin told him the complete story. After listening to the full situation Woojin finally said, 'It is indeed quite a very difficult situation for you, Noah. But I know of a way out, but first you must face the reality. All your Family members are dead, everything you loved in this world, your wife, your parents, your sister, your brother, everybody is dead, don't try to change the reality.' 'No, there are 3 people whom I love who are still alive, one is Robin, my best friend and the other 2 are my children, Rose and my children, Our children.'
