Background

　　It was a sunny summer afternoon. Betty came across an old friend Tom. They were surprised to see each other since they hadn’t met in a very long time. Tom invited Betty to their familiar café. They began to talk…

　　Tom: Oh, you are still charming, Betty.

　　Betty: Really? It’s already been six years since we last saw each other.

　　Tom: Yeah, time flies like the speed of an arrow.

　　You know, my current life tends to be busy and intensive.

　　Betty: Really? I have a relaxed and easy life.

　　Tom: Well, what do you do to kill time?

　　Betty:I like to go shopping and chat online.

　　Tom: To tell the truth, you have always been the girl of my dreams.

　　Betty: I can’t believe it!!

　　Tom: My dear, time will show you my heart…

　　Would you like to share your life with another person?

　　Betty: Who? I already have a boy in my mind.

　　Tom: What? You already have a boy in mind. But…

　　Betty: My love, you are that boy!
