Five years ago, he had no choice but to cut off his love with a heartless phone call; five years later, he met her at a painting exhibition in an old house in an old alley, and he worked every step of the way just to recover her that he had lost. A bowl of preserved egg and lean meat porridge, a piece of aged double skin milk, and a mottled graffiti wall are all obsessions that have been hidden for five years. The misunderstanding was solved, and the mind became clear. It turned out that the person I wanted to protect the most was always deep in the old alley. In the old days, we could not love each other, but in the new years, we will stay together for the rest of our lives.
