Quiet yet curious Campbell's hamster seeks a new home.

I got this Campbell's hamster from a friend last winter. He was moving and wouldn't be able to care for it anymore, so I temporarily took it home. At first, it was very timid; it would immediately scurry into its wooden house whenever someone approached. Later, it gradually adapted to its environment, and now it peeks out its little head to see what's happening whenever it hears someone approaching. It's especially active at night, often running around on its wheel for a long time, sometimes even moving its food around as if rearranging its little storehouse. It doesn't bite; you can easily handle it if you move slowly. Recently, I've been very busy with work and travel frequently, and I'm worried I won't have enough time to properly care for it, so I'm hoping to find it a more stable and quieter home.
