When he actually died at his hands, he realized how he had so much emotion to share with other people. He only loved him all the time. But even after he finally found that person, he realized that he never loved him, and he realized that everything was his arrangement, and his heart no longer belonged to him alone.
"When I found out that there were other people around you, I realized that I was not the most special one in your eyes. I have done many wrong things before, but you believe me! I will do my best to compensate you. I love you and I can't live without you."
"But your eyes have only been apart from me for a few years. You can even end my life with your own hands and peel off my dragon scales for a substitute. You say you love me? I did love you deeply when I was young, but we can't go back to the past. You should open your eyes and recognize the reality. I don't want to go through that level of suffering again."
