Character Runs Off Camera

Hello Unity3D i have a problem with my camera.The problem is my characters camera is auto targeting an enemy and whenever my character runs too far I can still see the enemy but i can't see the character that i have attached the camera to.What i want is no matter how far i go the camera still shows my character and the enemy.If anyone knows how i can do this.Can you please tell me how?

 var target : Transform;
 var moveSpeed = 20;
 var rotationSpeed = 5;
 var myTransform : Transform;
  
 function Awake() {
         myTransform = transform;
 }
  
 function Start() {
  
         target = GameObject.FindWithTag("Eye").transform;
 }
  
 function Update () {
    
     myTransform.rotation = Quaternion.Slerp(myTransform.rotation,
     Quaternion.LookRotation(target.position - myTransform.position), rotationSpeed*Time.deltaTime);
 }
