He is Clint, A novelist who unexpectedly became famous because of the story he wrote. That Story is based on his relationship with a young man that soon ended up in separation. He actually Dedicated it for him-for Yuan.
But in that story, Clint decided to change the ending of the story to make it a happy ending even though in his real story it didn't really end up with a happy ending.
When he sat on a big rock, he looked up and there he saw the amethyst-like moon. Thinking it granted wishes Clint made a request without thinking twice. He closed both his eyes and began to wish. But, in the middle of his wishing request, a human figure appeared in front of him. He looked up to find out who it was but because of the purple color from the moonlight hitting the man's glasses he couldn't see it well so he stood up and faced the man standing next to him. Because he is taller than Clint, he looked up again and there he had the courage to remove the man's eye glasses and there, unexpectedly, his wish began to come true... He was Yuan, His Ex-Boyfriend came back.
