Even though we were together so hard, I still lost you in the end.
I'm sorry that I couldn't protect you all the time.
I will no longer love you, I will no longer be immersed in your memories, I must move on. I will spend my whole life practicing forgetting you and falling in love with my wife. When she and I were both too old to walk, I lay on the rocking chair, showed her your photo, and said, this is the person I loved deeply when I was young. I'm sorry that I only loved you for decades and did not give you all my life's love.
In the middle, this is the ending for me and you. This is the most beautiful ending I can think of.
