Trying to replace a simple toggle switch for the bath fan with a timer switch.

The wiring in the box is 2wire (black/white/ground) which works great with the toggle switch.

The timer switch I want to replace it with has black/white/red/ with a grounding nut.

The red wire is the "load" wire, but......where do I attach it to? It seems the white wire is the load wire coming into the box from the fan. So if that's the case, where do I attach the neutral wire from the switch to? The only possible place I can think of is ground, but is that right/safe?
