The Fifteenth Ugly Duckling

My poems started, I went on a long journey alone and worked hard on the website. I am not alone, there is someone who is always with me, helping me, enlightening me, motivating me and comforting me. Accompany me day and night, accompany me to tears of joy. He asked me not to say anything about him, but I wrote him into poems and put him in the treasure map. You can guess slowly. Don't be discouraged if you can't guess, the clues are endless. Don't say anything you guessed, let others continue to guess. For the last song, I will announce the results. Anyway, I won't be here later, so it doesn't count as a violation of his agreement.
