how to get POST and COMMENT fields at single page

i need to get comment's that ralation with my post just like real websites

My DB Tables: posts , comments.tags ...

POST model :

 public function comments()
{
    return  $this->belongsTo(Comment::class);
}
  public function tags()
{
    return  $this->belongsTo(Tag::class);
}
 ....

Comment Model :

public function posts()
{
    return  $this->hasMany(Post::class);
}

Controller index function

public function index()
{
    $posts =Post::all();
    return view('rel',compact('posts'));
}

view :

here my output:

as you can see,i have an array with 2 value ( have 2 Post at my table )

and have 2 comment that relation with my post

i need to access to POST field and Comments Field at single page

of course in future i need tag's too
