Falling Iron: Watching Movies and Happy Gray Series

I'm a newbie, hoping to write a story that everyone will like. There is only the Gray Wolf Red Wolf CP combination, no other CPs. No harem, no ambiguity. Big Big Wolf was doing experiments in the laboratory. Due to an accident, the time and space shuttle machine was activated. Through the chaotic time and space tunnel, Big Big Wolf arrived at the Star Dome Railway World, where he met new partners and learned about the new world. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
