[Basic Three] It's Not Easy to Get to Know Each Other

Traveling with the system, the protagonist CP is Cang Ge [BG] (emphasis added) In the whole drama, only the two protagonists travel through time. Supporting characters will have CPs of various sexual orientations I haven't come up with an outline yet, so I'll just write it wherever I go. If you have any CPs, plots, jokes, etc. You want to see, you can leave a message. I'll try my best to write it, but I will never touch NPCs! I can't write well... At most I can let the NPCs appear or something.
