What is happiness? I don't know, I only know that there is someone standing in front of the gate of heaven, just one step away but never able to cross. I watched with my own eyes my young lady, Master Luo and brother and sister Han Fei, ups and downs in the entanglement of love and hate, struggling hard but only falling deeper and deeper. What is happiness? Is it the young lady's smile before her death or the sad melody that the young master plays every day? What is happiness? I hope that after listening to my story, you can tell me, let me tell the lady in heaven, what happiness is. This was the only request from the maid who told me this story.
