How to make additional communication in Laravel?

Question

Laravel

The model has two functions

public function variant(){
  return $this->belongsTo('App\Variant')->whereHas('product', function ($query) {
    $query->where('visible', 1);
  });
}

public function varianto(){
  return $this->belongsTo('App\Variant')->whereHas('product', function ($query) {
    $query->where('visible', 1);
  });
}

in template

@foreach($order->items as $item)
  @if($i++)
    <hr>
  @endif

  {{ $item->variant }}1
  {{ $item->varianto }}2
@endforeach

$item->variant - A variant object arrives,
$item->varianto - Null
