Suddenly one day, I suddenly thought of you, our past and the memories we had walked together, and I suddenly lost myself... It wasn't you that made me bad, it wasn't you that I didn't wait for, why didn't you say that I love you in the end. Some people say that the regret between men and women comes from not saying anything even to death and pretending not to know. But I didn't expect that we would execute it so thoroughly.
