Why doesn't the awake function work in this case?

Hello, I have no other way of asking this than: Why doesn’t this work?

using UnityEngine;
public class TestScript : MonoBehaviour {

	void Update(){
		Debug.Log("This one works, obviously.");
	}

	public class TestClass_1{
		void Awake(){
			Debug.Log("This one doesn't work. Why?");
		}
	}
	
}

It doesn’t work because your TestClass_1 doesn’t derive from MonoBehaviour, which is where the Awake method is found. You can make your class derive from MonoBehaviour by changing your class declaration to

public class TestClass_1 : MonoBehaviour
{
         void Awake()
         {
             Debug.Log("This one doesn't work. Why?");
         }
}

Even after you do this, it won’t run like you expect because you still need to create an instance of the class. When a script derives from MonoBehaiour, Unity doesn’t allow you create a new instance in the normal way. Instead, you need to add the class as a component of your gameobject.

using UnityEngine;
public class TestScript : MonoBehaviour
{
    void Awake()
    {
        gameObject.AddComponent<TestClass_1>();
    }

    void Update()
    {
        Debug.Log("This one works, obviously.");
    }

    public class TestClass_1 : MonoBehaviour
    {
        void Awake()
        {
            Debug.Log("This one doesn't work. Why?");
        }
    }
}

This should print out

This one doesn’t work. Why?
and then:
This one works, obviously.
over and over and over again.
