joining tables in laravel elequent

how can i join those two tables in laravel elequent and make them as one table ?

Table 1(base info ) :

id  baseId   Site_ID  region    city        address
1     123      321     west    wakanda      street2

Table 2(basecounts) :

base_id     First     Second   third  
1            54          52     51

i have those two models idk if they are correct or not :

class base extends Model
{
    public function Counts() {
    return $this->hasOne(CountInBase::class, 'base_id');
}

}

class CountInBase extends Model
{
    public function bases() {
        return $this->belongsTo(base::class ,'base_id','id');
    }
}

in controller i am trying to make this query but i am not getting the expacted result , i am just getting the results of the first table :

$data = base::where('region' ,'=' ,'west')->with(['Counts'])->get();
