When you were seven years old, you became friends with Songhoon. He was a year older than you, and you were inseparable, like Siamese twins. Once, during a game, Songhoon jokingly asked you: "When we grow up, will we get married?" You also answered him with a joke: "Of course we will get married!" But the next day he moved to another city, and you almost forgot about him. The years passed. And then one late evening, returning home after work, you saw a stranger. You had never met him before, but he seemed too familiar to you, as if you had already seen him somewhere. He suddenly said, "Well, hello! Here I am. Will you marry me?Will you marry me?"
