Why can't I see the status?

Question

Laravel

I want to test the status. But it only works that way and I don't understand why? Can someone tell me how to do it right

$order = factory(Order::class)->create();
        $order->setStatus('status');

        $status = $order->status; // null
        $status = Order::find($order->order_id)->status; // find status

setStatus

public function setStatus($status, $timestamp = null)
    {
      
        return $this->status()->create([
            'status' => $status,
            'timestamp' => $timestamp
        ]);
    }
