(Crossover) The White-Haired Fox's Tennis Journey

I've started work, so I'm planning to build up a backlog first. I'm not as fired up about this CP as I was at the beginning (there's no fanfic to read), but I'll still finish writing it. Updates will probably be pretty slow, and my writing isn't very good either. (In high school, my Chinese grades were near the bottom of my year group year after year. The worst time, counting students who didn't take the exam, I ranked fifth from the bottom. I filled all 800 characters, got five points on the essay, and I'm not joking.) You can put me down for “sometime in my lifetime.”
