Cube rolling problem (rotation problem)

Question

Hi, I want to make a rolling cube around its edges, it kinda works, it gives the illusion it rolls well.

Here's a gif :

But the thing is, when it gets colored, I can see it's not rolling as well as I thought. It's like it is rotating around to axis at the same time.

Here is the roll function.

 IEnumerator Roll (Vector3 direction)
     {
         input = false;
 
         float rollDecimal = 0;
         float rollAngle = 90;
         float oldAngle = 0;
         float halfWidth = transform.localScale.x /2;
 
         Vector3 rollAxis = Vector3.Cross(Vector3.up, direction);
         Vector3 pointAround = transform.position + (Vector3.down * halfWidth) + (direction * halfWidth);
 
         Quaternion rotation = transform.rotation;
         Quaternion endRotation = rotation * Quaternion.Euler(rollAxis * rollAngle);
         Vector3 endPosition = transform.position + direction;
 
         while (rollDecimal < speed)
         {
             yield return new WaitForEndOfFrame();
             rollDecimal += Time.deltaTime;
             float newAngle = (rollDecimal / speed) * rollAngle;
             float rotateThrough = newAngle - oldAngle;
             oldAngle = newAngle;
             transform.RotateAround(pointAround, rollAxis, rotateThrough);
         }
         transform.position = endPosition;
         transform.rotation = endRotation;
 
         input = true;
 
     }

Thanks in advance,
