This is my own take, and my writing is amateurish. I'm mainly writing to please myself, so please don't complain if it's not to your taste. I want to add some melodrama in the middle, hehehe. I dreamed up this scene: Xiuhan will have their memories of each other erased. Hmm, a final counterattack in the plot? Who knows. Maybe I'll add one, maybe I won't.
Are they all Xiu Hehan?
