"I have always firmly believed that I am just a lonely 'ghost' among all living beings. Like most 'ghosts', there is nothing strange, until I met the only 'person' in the world that is only related to me on an inconspicuous evening. However, in contrast, I prefer to call him my 'soul'." - Zhang Jia's diary
Concept: Love is the most beautiful emotion that can be encountered in real life. It is not so easy to encounter, but the world is so big, there is always someone who is tailor-made for you. And there is more than one interpretation of love. "Compatible souls" is the purest form of love in my opinion.
