not the one

Someone else instead

Not the one dismisses something or someone as wrong, inadequate, or not what's being sought.

It rejects a specific item from consideration: That's not the one I ordered.

In dating contexts, it declares someone isn't a suitable long-term partner: He was sweet, but not the one.

The phrase implies a correct choice exists elsewhere.
