What happens to charge stored in a capacitor when moving the plates?

[AdityaDev]

Let us take a charged capacitor and move the plates such that it the distance between them be constant. For example, one moves towards left and other moves upwards.
Assuming only overlapping area affects capacitance... WILL THE CHARGE STORED IN CAPACITOR CHANGE?
I know the capacitance changes.

Is the capacitor still connected to a voltage source or not connected to anything?

U = QC is valid in both cases, but in the first case U is constant and in the second case Q.

The capacitor is not connected to anything... hence the net charge in the capacitor plates should be same. But potential difference changes.
