Why the MoveTowards make the transform moving nonstop?

Question

In the Update in the else part, I'm trying to move the transform up from its current position on the exit more up by offset.

When the flag bool exit is true I want the transform to move up more by the offset for example if the offset is 7 then move up on the Y more 7. but it's moving up non-stop.

I tried to like this with exitPosition variable for storing at exit: but still, it's moving up non-stop.

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;

public class Testing : MonoBehaviour
{
    public float speed;
    public float offset;

    private bool exited = false;
    private Vector3 exitPosition;

    private void Start()
    {
        Debug.Log("Position : " + transform.position);
    }

    private void OnTriggerExit(Collider other)
    {
        if (other.name == "Cube")
        {
            Debug.Log("Exited !");
        }

        exitPosition = new Vector3(transform.position.x,
                transform.position.y + offset, transform.position.z);

        exited = true;
    }

    private void Update()
    {
        if (!exited)
        {
            transform.position += Vector3.up * speed * Time.deltaTime;
        }
        else
        {
            transform.position = Vector3.MoveTowards(transform.position, exitPosition, speed * Time.deltaTime);
        }
    }
}

Just make sure your exitPosition is set only once:

private void OnTriggerExit(Collider other)
{
    if (other.name == "Cube" && exited == false)
    {
        Debug.Log("Exited !");
        exitPosition = new Vector3(transform.position.x,transform.position.y + offset,transform.position.z);
        exited = true;
   }
}
