The original outline of this article - ah, no, that guy never asked for an outline - was supposed to be that when the original author conceived it, one of the two protagonists died and the other was a paraplegic. But in order to celebrate my birthday, and for some reasons involving blood and tears... In short, I changed the ending. Readers are advised to proceed with caution. I don't like to comment too much. I will try my best to correct it.
