[Ziyu] Tracing the Old Days

Bringing over some fun. Like Saltwater Room, this is NGC123's melon tree (if you don't understand, see my profile page).

The premise is a little hard to explain. Just read it?

I recommend reading carefully, or you might not understand... ummm.

I'll add a simple explanation after the final chapter. If you still don't get it, there's no after-sales service (nyah nyah nyah nyah b(￣▽￣)d).
