[Sherlock/john]light and Shadow(abo)

Rating: N-17 Background: This story is set in the world view of ABO (if you don't know what race ABO is, please check it out, sorry). The plot is based on the BBC's Sherlock reasoning as much as possible, so there will be a lot of overlapping scenes and lines (readers who can't accept it, please XX, but I promise it will be different as you go later). The most important thing is to explore the steadfast love between Sherlock and John. Synopsis: John Hamish Watson is a Onega race with a Beta appearance and a rare constitution. Before meeting Sherlock Holmes (Alpha race), he had been living an ordinary Beta life. In a world where light and shadow intersect, how can the two overcome all difficulties and compose a moving rainbow music, and finally get married? … Note: I use Sherlock and John here, because I think using "John" in H is quite boring... Warning: Since the Traditional Chinese WORD is directly converted into Simplified Chinese, the author does not know whether there are as many typos as a mountain. Please forgive me and bow down with gratitude!
